いつだったか、あれから一体どれだけ時が経ったのだろうか......。
僕はあの日から、人生が変わった。
今まであったものが全部なくなった。
いや、辛うじて残った物や友人もいた。
だが、多分、全部失くしたという人が大半だと思う。
あの日、僕の祖国は滅びた。
文字通り、滅びた。
天災などであればまだよかった。
他国からの侵略。
慈悲の無い殺戮。
守るべき民も守れず、父である王も、母である王妃も、姉であった王女も皆死んだ。
だが、僕だけは一人の侍女......いや、姉の友人にも等しい彼女と共に、自分達だけ生き残ってしまった。
......僕はその日、ダンジョンマスターとなって生きながらえた。
彼女が手を引いて何とか僕を逃がそうとしていてくれたが、それは不可能に近く、逃げ込んだ倉庫にも敵の手が伸びようとしていた。
その時、僕は神を名乗る女性からダンジョンマスターの能力を得た。
「生きたい? ならその力を使いなさい。代償はそうね...とりあえずまずはそのダンジョンマスターの能力をつかいこなしてからよ」
何が何だかわからなかった。
だけど、ダンジョンマスターのスキルの使い方はなんとなくわかった。
だから、即座に倉庫に小さなダンジョンへの通路を作り、必死に逃げ込んだ。
追ってきた兵士は罠で殺し、魔物で殺した。
そして、彼女と一緒に、ダンジョンの中で息をひそめて、幾日か過ぎ、外の様子を伺えば......。
城は崩れ、街は焼け、生き残りは一人としていなかった。
そして僕は彼女と一緒に元領地を見て回った。
でも、そこも全て焼き払われていた。
生き残りもいなかった。
いや、生き残りがいるのならもう逃げているだろう。
「坊ちゃま......どうされますか?」
「......ここまでとは思わなかった...。ねえ、アンナ。近くの他国までどの位だい?」
「......そう、ですね。私達の足で......二か月はかかるかと......」
「...そうか。今のままの僕達じゃ危険だね......」
僕は何とか自分の状況を判断する。
今のまま他国に行ってもただの難民扱いだろう。
むしろ、自分が王子と言っても証明できないし、安全だとも限らない......。
「アンナ。聞いてくれ、僕はしばらく王都の下のダンジョンで力を蓄えようと思うんだ。父も母も...民も弔ってやりたいし......どうかな?」
「ご立派なご判断かと思います。このアンナ最後まで坊ちゃまと一緒にいきます」
「......ありがとう」
そうやって、僕とアンナは再び王都のダンジョンへ戻り、魔物を使役して、瓦礫を片付け、皆の遺体を弔ってやった。
墓荒しが出ても守るものなどいないので、申し訳ないが、皆の墓はダンジョン内の一室へと安置させてもらった。
しばらく時が経った。
滅びた王都は風化し、そこに宝を求める冒険者達が押し寄せてきていた。
「坊ちゃま。また侵入者です」
「またか、そっとしておいてくれないんだな。いつもの通り迎撃をする。奴隷などで酷い扱いを受けているようなら保護するように」
僕がそう指示をすると、デュラハンが敬礼で返事をし、その場を離れる。
「彼とも、長い付き合いになりましたね」
「ああ、王都が落ちてからずっと僕達を守ってくれている」
デュラハンは、あの王都が落ちた時、僕がDPの消費も考えずに、一番強そうな魔物を呼び出した結果なのだ。
レベルは何と130で、伝説の勇者や魔王、それらと肩を並べる程の魔物だ。
今までのダンジョンでの防衛で150まで上がっている。
そうやって、デュラハンを見送っていると、別の方向、居住場所から小さい女の子がこちらに駆け寄ってくる。
「ライエ様。デュラハンさんは?」
キョロキョロとあたりを見回して、デュラハンを探してる女の子。
彼女は、ここのダンジョン攻略へ来た冒険者が只のおとりとして、引き連れてきた女の子だった。
アンナと何度か話し合って、なんとか外の人間と連絡を取りたいと思っていたが、冒険者は信用できない。
何度か、話し合いを設けようとしたが、魔物として、斬りかかってきたり、アンナを人質に取ろうとしたりで、上手くいかなかった。
そんな中で唯一、僕達の味方になってくれている大事な家族だ。
「リーリ。彼はお仕事にいきましたよ」
「えー!? 私も追いかける!! 剣を使って冒険者を倒す!! ライエ様やアンナさん、デュラハンさんを虐める奴は許さないんだから!!」
「あー、落ち着いて。大丈夫だから、ね?」
「ええ、彼はとても強いですからね」
そうやって日々が過ぎていく。
いつか、話し合える誰かがくると信じて。
「ライエ様、今日で225年です」
「良く数えてるな。僕はもう200年ぐらいしか感覚がないよ。アンナも若いままだし」
「私としては見慣れたけど、不思議だよね。もう私も182歳だよ。もうびっくり」
あれからアンナの数えで225年も経っていた。
僕が作ったダンジョンはそこを中心に町ができ、冒険者ギルドができ、大いににぎわっていた。
仲間はあれから増えたり減ったりの繰り返しだ。
ダンジョンマスターの権限で、不老にすることはできるが、なかなか不老を望むモノはいなかった。
外的要因で死ぬことはあっても、体の衰えや病気で死ぬことが無くなったので、自分が人間でない何かになりたくはないのが主な理由だった。
この町も、このダンジョンで助けた奴隷の一団がここで町を作ると頑張ってくれた結果だ。
「しつこいかもしれないけど......」
「私は不老になった事を悔いてはおりません」
「私も不老になった事を気にしてないよ。むしろ、ライエ様やアンナさんを食べ放題だし......ふへへ」
「こほん。リーリ、あまりそういう事は......」
「はーい、ごめんなさい」
ま、姿は変わらないけど男としての、女としての生理現象や欲求はあるので、この3人で仲良くしている。
子供は自分たちの立場が立場だから、作れてはいないが、いつか欲しいとは思う。
「さーて、私はいつもの通り冒険者ギルドにいってくるよ」
「はい、リーリ気を付けて」
「買い物もよろしく」
今では冒険者ギルドに定期的リーリが出入りをして、素材を換金しては、外の町の品物を買ってくる循環ができている。
不老とばれるとまずいので30年周期ぐらいで10年、外にでない時期はあるのだが、今は活動時期だ。
リーリもあれから強くなったものでレベル150とかつてのデュラハンと同じぐらいになっている。
因みに現在デュラハンのレベルは310と、もう勇者でも魔王でも何でも来いと思う。
なるほど、これはダンジョンが天災と言われるのも分かった気がする。
そして、その日は僕達にとって運命の日となった......。
「なっ!?」
僕と、アンナがそろって声を上げる。
「ど、どういう事です!? あ、あり得ない!?」
「だ、ダンジョンの制御ができない!? う、奪われてる!?」
そう、その日も攻略をしている冒険者達を監視している所だった。
そして、大体7分事に制御できなくなる階層が増えていく。
「アンナ、今侵入している冒険者の数は!!」
「はい、確認しているのは55名です!!」
「全員ステータスを調べ上げろ。何か変なのが混じってるぞ!!」
「わかりました。リーリにもドッペルをつかって連絡をやります!!」
「頼む!!」
だが、無情にもダンジョンの制御が徐々に奪われていく。
5時間。
たった5時間で全階層50階のダンジョンが47階層まで制御不能となった。
「......なんなんだいったい」
「坊ちゃま、大丈夫です。リーリとデュラハンが迎撃に行っているはずです」
「ああ、デュラハンが負けるとは思えないけど...リーリは大丈夫だろうか......」
「彼女は頑張って私達よりもレベルは上です。きっと大丈夫ですよ。それに、今まで鍛えてきた精鋭の魔物も放っております」
「くそっ、こんな事なら僕もレベルを上げていれば......!!」
「それはなりません。ダンジョンマスターである坊ちゃまがいてこそ、皆力がだせるのです。坊ちゃまは王者として、最後まで私達に指示をしてくれればよいのです」
「でもっ」
「何度も話はしたはずです。私もリーリもライエ様を生かすためなら命を捨てる覚悟です。ライエ様も約束したではありませんか、必ず生き延びると」
「......ああ」
頼む。
皆無事でいてくれ。
僕が悪かったのか?
ダンジョンマスターという力に胡坐をかいてた罰なのか?
ダンジョンの制御ができなくなるんて......、この力を与えたあの声の持ち主は何を考えて僕にこの力を渡したのか......。
今更ながら、この力の意味を考えていたのだった。
side:リーリ・ル・コッセル
今日も同じ日のはずだった。
ただ冒険者ギルドにいって素材を換金して、買い物をするそれだけのはずだった。
「おう、まだ生きてたか」
「酷いなー、これでもランク7の冒険者だぞ」
「信じられねーよな。ソロでランク7とか、ダンジョンにずっともぐりっぱなしじゃ、死んでるとおもうって」
いつもの買取カウンターでの会話。
私は長い事生きているので、この町の変わりようも見てきた。
でも、今の私はこの町に居ついて5・6年の冒険者。
こんな事をもう何度も繰り返している。
あの小さかった頃の体はなく、メリハリのついた立派な女性の体つきになってる。
ライエ様も気持ちよさそうだし、今の状況に不満はないかな。
そんな事を考えていると、ギルドマスターの部屋から数人の...貴族みたいな人たちが出てきた。
「ねぇ、あの人たちは?」
「ん? ああ、なんかどこぞのお偉いさんでダンジョンの見学にきたとさ。俺からすれば、間違って死んで町に難癖つけられないか不安なんだよな」
「へぇ~」
そうやって、その人たちを見る。
なんともまあ、私が見てもため息をつくほどの美人ばかり。
その中で一人だけ男。
なんというかパッとしないが、多分周りは彼の奴隷か、連れなのだろう。
ダンジョン内で、彼女達にひどい仕打ちでもしてみろ、すぐさま首を切り落としてやる。
「ほい、金貨4枚な」
「ありがと」
「また買い物して、しばらくダンジョンか?」
「......お前みたいな器量よしなら男は選び放題だろうに、無理すんなよ」
「残念。私はもう心に決めた人がいるんだなー。でも忠告ありがと」
そうやってギルドをでて適当に買い物をしていると、連絡用のドッペルが駆け寄ってきた。
「どうしたの?」
「ダンジョンに異常事態。至急戻られたし」
「わかったわ」
私は即座に身をひるがえしてダンジョンへと戻る。
そこで聞いたのはダンジョンの制御が奪われているとの事。
状況からみて、侵入してきた冒険者の仕業と判断。
なので、現在侵入が確認できている冒険者の排除...殺害を開始すると。
総出で、現在確認できる冒険者共を屠っていった。
知り合いの冒険者もいた。
全部コロシた。
当たり前だ、私達の大事な場所を汚されてたまるか。
だが、ダンジョンの制御はどんどん失われていく。
「......そうね。48階にみんな集まって。いま制御が残ってるのはそれより下の階層。もう、45、46階は時間的に間に合いそうにない。いいかな、デュラハンさん?」
長年の友でもあり、私にとっては父の様な存在であるデュラハンさんは、剣を振り同意を示した。
「よし、みんな階段入口で待ち構えて、来た冒険者を確実に仕留めるよ!!」
「「「オオー!!」」」
そして私の予想通り、原因と思われる冒険者たちが降りてきた。
彼等が降りてきた瞬間にダンジョンのMAPが見れなくなった......、こいつらか。
「そうね、ようやくいい運動になりそうね」
「...ユキは下がる」
「え? え? ここは普通男が前に出るもんじゃね?」
「首輪をつけて下げるわよ?」
「...ちょっと待ってください。セラリア、首輪つけてするプレイとかどうです?」
「...でもいいかもしれませんね。旦那様が首輪をつけて...はぁ」
「やめれ!? 俺はそんな趣味ないぞ!?」
そんな雑談をしている彼等に魔物たちは歯がたたなかった。
和やかに会話をしながら、レベル100近い魔物たちがなすすべもなく、崩れ落ちる。
私が呆けている間に、デュラハンさんが飛び出る。
「おい、そのデュラハン別格だ!! レベル300超え!!」
彼等は反応できていない。
さっきの貴族の様な気もするが、ここで仕留めておかないと危険だ。
私もデュラハンさんを追って追撃を......
「伊達にデリーユと訓練はしていないわよ。この程度のレベル差で私は止められないわ」
綺麗な銀髪をなびかせて、不思議な剣を鞘へと戻す音が響く。
「あ、ああっ!!」
デュラハンさんが...消えて......!?
こいつらだけは絶対!!
ごめん、ライエ様、アンナさん。
引けないや、ごめん。
ライエ様、貴方にもらった家名。
姉と同じ家名を私に下さったこと感謝しています。
その家名、返す時が来たようです。
ですが、願わくば、貴方の傍でずっと笑っていたかった。
「我が主のダンジョンをこれ以上汚す事は許さん!! これ以上進むなら、このリーリ・ル・コッセルを倒してからいけ!!」
最後の咆哮。
デュラハンさんをあっさり倒した彼女に私は勝てるわけないだろう。
それでも...私は最後まで抗う。
そうやって剣を握りしめ、相手の隙を伺う。
「「「ル・コッセル!?」」」
なぜか相手は首を傾げ、驚いていた。
なんでだろう?
Side: ???
When was it, how much time has pa.s.sed since then......?
From that day onward, my life changed.
All the things that I had known disappeared that day.
No, there was something... a friend remains.
But, alas most of the people I can remember are gone.
That day, my homeland fell to ruin.
It completely perished.
If it had been a natural disaster I could have at least said, It can't be helped. But the cause was war... People.
It was an invasion from another country.
...Merciless heresy, slaughter, destruction.
It was impossible to protect the people of our nation... my father the King, my mother the Queen, my sister the Princess and everyone else... they all died.
But I1) survived together with a single maid...... No, more than a maid she was my sister's friend, together with her... It was us and us alone who survived that day.
While trying to survive I became a Dungeon Master.
That girl I was escaping with took the lead for some reason, but just like for everyone else, escape was impossible. The enemy had surrounded the warehouse we escaped to and were just moments away from breaking in.
At that moment, I received the abilities of a Dungeon Master from a woman who called herself G.o.ddess.
[Do you want to live? ...Then use this power. The compensation is... Since time is short, let's jump straight to the abilities of a Dungeon Master. ] 
...I didn't really understand much of it.
But I figured out how to use the skills of a Dungeon Master.
So I instantly made a small Dungeon in the warehouse and desperately escaped into it.
After a long and brutal struggle, we managed to kill all those hateful soldiers who chased us with traps and monsters.
Then, together with that girl, I started calming down and catching my breath inside the Dungeon. After a few days pa.s.sed, I started getting curious about the state outside and went to have a look.....
It was all gone. It looked like someone had summoned h.e.l.l right on top of our beloved City, destroying all and killing all. The castle was reduced to a red pile of rubble and seemed to have been used as an execution grounds, the streets were still burning and almost as if it was as natural as having air to breath, there weren't any survivors.
After another day we used to recover our mental strength, that girl and I ended up looking around our former territory together.
But no matter, where we went, it was the same scene... everything had been burned away.
...No survivors.
No, when I think about it, there must have been survivors... after all, killing an entire nations worth of people is an almost impossible task. So I hope that they had already run away and I was simply lacking in ability to find anyone.
(???)[Young master... What should we do?] 
(???)[...... I never thought that even here... Hey, Anna. 2)How far are we from other countries?] 
(Anna)[...... Let's see. On foot....... It would take around two months..... ] 
(???)[... Really. As we are now, that's not really possible since we've already used most of our reserves..... ] 
I vaguely understood our situation.
Even if we go to another country after this, we would only be treated as refugees.
More to the point, I can't even say that I am a prince, in other words I can't guarantee our safety... even slavery is a possibility.
(???)[Anna. Listen, I think I will store up power in the Dun
(Anna)[I think that's a nice idea. This Anna will stay together with the Young Master to the end. ] 
(???)[...... Thank you. ] 
With that, Anna and I returned to our Dungeon inside the Royal Capital. We used the monsters there to clear away the rubble, bury the dead and mourn everyone lost.
I felt sorry for any random people that came and reacted to the monsters with hostility, but everyone's now resting inside the Dungeon so it was worth it. Besides most of those random people were probably from "there"3).
For awhile, time pa.s.sed relatively peacefully just like that4).
The ruined Capital was slowly weathered and forgotten. Eventually adventurers came charging in while seeking treasures.
(Anna)[Young Master. Another intruder. ] 
(???)[Once again, make them leave quietly. Intercept them as usual. If there are any slaves receiving cruel treatment, then protect them. ] 
On my instruction, the Dullahan 5) salutes before leaving.
(Anna)[Our relations.h.i.+p with him has been a long one. ] 
(???)[Yes, he has protected us ever since the Royal Capital fell. ] 
Dullahan is the result of summoning the strongest Demon, after the Kingdom fell. The DP cost was all of it, but at the time I didn't think twice about it
His level was 130 and he could stand shoulder to shoulder with the legendary Heroes and maybe even a Demon King.
Now, after countless battles in the Dungeon, his level has risen to 150.
Like that, when I saw Dullahan off, a small girl rushed over from another direction.
(Anna)[Raie6)-sama. Where is Dullahan-san?] 
A girl is looking around restlessly, searching for Dullahan.
This girl was, according to the plan of the adventurers who brought her, going to be used as a decoy if they were to find themselves in a tight spot.
I had discussed it with Anna several times and we wanted to get in touch with someone from the outside to get her out, but adventurers cannot be trusted.
We tried to set up peaceful discussions many times, but being seen as monsters, they came in trying to slaughter us and took Anna as a hostage, they regretted that though.
That said, she is now our important family member.
(Raie)[Lilli. He went out to work. ] 
(Lilli)[Eh!? I'll also go!! I'll defeat the adventurers!! Raie-sama, Anna-san and Dullahan-san. No one has the right to bully any of you!! ] 
(Raie)[Ah, calm down. It will be fine, okay?] 
(Raie)[Yes, he is very strong. ] 
And that's how our daily lives went.
...Someday, I believed someone would come and talk to us.
(Anna)[Raie-sama, today marks 225 years. ] 
(Raie)[You're not counting well. I have the feeling that I have experienced close to twenty years. Anna too is also young. ] 
(Lili)[Though it's strange, I got used to it. Mou, I'm 182 years old now. Really, how surprising! ] 
It's been 225 years since Anna started counting the age of the Dungeon.
The Dungeon I made now has a town built around it, there is also an Adventurer Guild and it's very crowded.
We are now in a state of constant increase and decrease in my comrades. 7)
With my authority as a Dungeon Master, I could grant them eternal youth. But there weren't many people who wished for that.
Even if they can still die from external causes, the main reason is that they don't want to become something that isn't human anymore. Bodies that don't age or succ.u.mb to illness, I can understand their feelings.
This village is the result of a group of slaves trying hard to help in the Dungeon to make a home. In the end, no one has reached this place to talk to us before meeting their demise.
(Raie)[It might be selfish, but...... ] 
(Anna)[I do not regret having perpetual youth now. ] 
(Lilli)[No, I don't mind boasting of perpetual youth. It would be better though, if I could use it for an all-you-can-eat Raina-sama8) and Anna-san...... Fuee!] 
(Raie)[*Cough* Lilli9), enough of that ...... ] 
(Lilli)[Aaww, I'm sorry. ] 
Well, even if my figure doesn't age beyond that of a child, I'm still a man and I naturally have natural urges and desires pertaining women, those 3 are my friends.
In consideration of a child, I think we can't do it, but I think that I still want to do it one day.
(Lilli)[Well then, I'm off to the Adventurer Guild. ] 
(Raie)[Yes, be careful Lilli. ] 
(Anna)[Please remember to do some shopping. ] 
Today as well, Lilli is going through her routine. She's visiting the Adventurer Guild to cash in some materials and bring back some articles from the town outside.
Because it'd be bad if it's discovered by anyone that she has eternal youth, every 30 years there's about 10 years where she doesn't go outside, but right now is her activity time.
Lilli is also becoming stronger, she's now level 150, stronger than Dullahan was in the beginning.
Incidentally, Dullahan is now level 310. I think if a Demon King or a Hero were to come, they wouldn't be able to stand a chance against him.
I see, that's what they mean by natural disaster.
And today is a fateful day for us......
(Anna)[What!?] 
Anna's and my voices went loud.
(Anna)[What the!? Isn't that impossible!?] 
(Raie)[We ca-cannot control the Dungeon!? Does that mean it's being s.n.a.t.c.hed away!?] 
That very same day, right when I was monitoring the adventurers who were trying to capture the Dungeon, I noticed an abnormality, I lost control of the first floor for some reason......
And then, the number of floors I can control decreased every 7 minutes.
(Raie)[Anna, there are adventurers breaking in right?! Check them! ] 
(Anna)[Yes, I've confirmed it, 55 adventurers in total!! ] 
(Raie)[Inspect everyone's status. Someone or something strange must be mixed in!! ] 
(Anna)[Very well. I'll try contacting Lilli using a Doppel as well. ! ] 
(Raie)[Please!! ] 
However, control of the Dungeon is mercilessly disappearing.
...5 hours.
That's the time it took them to overthrow my control down to the 47th out of 50 floors.
(Raie)[....... Wh-what the heck?] 
(Anna)[Young Master, it'll be alright. Lilli and Dullahan will intercept them. ] 
(Raie)[Yes, I don't think Dullahan will be defeated but... Please be safe Lilli...... ] 
(Anna)[She does her best and her level is above ours. She's definitely safe. Besides, I'm giving them the elite monster I have trained as bodyguards. ] 
(Raie)[Kuso, if only I raised my level too....!!] 
(Anna)[That won't do. Young Master is the Dungeon Master and as a ruler you should be giving us instructions until the very end. ] 
(Raie)[But. ] 
(Anna)[We have talked about this many times already. Lilli and I are also ready to forfeit our lives anytime for Raie-sama's sake. And if that happens, Raie-sama must not break his promise, you definitely have to survive. ] 
(Raie)[...... Ah. ] 
Please.
Everyone be safe.
Was I wrong?
Is this punishment because I relied too much on the powers of a Dungeon Master?
I can't control the Dungeon anymore....... What did the owner of that voice who gave me this power say at that time......
Even now, I am thinking about the meaning behind this power.
Side : Lilli*Le* Kossel 10)
Today should've been the same as usual but it's not.
I had just visited the Adventurer Guild to cash in some materials and as usual I was in the middle of shopping.
(Shopkeeper)[Ou, you're still alive. ] 
(Lilli)[You're mean ~ Even though I look like this I'm a rank 7 adventurer. ] 
(Shopkeeper)[I just can't believe it. Even if you're rank 7, to go all the way inside the Dungeon alone... we can only a.s.sume you'd die. ] 
It was the usual conversation with the person behind the counter.
Because I have lived for so long, I have also seen the changes inside this town.
But currently, I've been an adventurer in this town for somewhere between 5 and 6 years.
I have repeated this kind of routine over and over again.
There is no more signs of the childlike body from that time, Instead, my body has become wonderful and womanly11)
It's all for the purpose of seducing Raie-sama, but I wonder if he's dissatisfied with the current situation.
While I was thinking about such things, several people came out from the Guildmaster's room... People resembling n.o.bles.
(Lilli)[Say, who are those people?] 
(Shopkeeper)[Uh? Oh, some sort of big shots that came to explore the Dungeon. If you want to know what I think, I'm worried that they'll die from some small mistake and that they'll bring trouble to the town] 
(Lilli)[Eeeh~] 
Hearing that, I look at the other party.
Anyhow, there are some beauties to the extent that even I let out a sigh.
Only one of them is a man.
I don't know why but I am vaguely dissatisfied. Perhaps they are his slaves that he is showing off.
If while they enter the Dungeon and he treats them badly, I will immediately dispose of him.
(Saler)[Yes, it's 4 gold coins. ] 
(Lilli)[Thank you. ] 
(Saler)[Seeing you shopping again, are you going to stay inside the Dungeon for a while?] 
(Saler)[...... If it's you and your abilities, there would definitely be plenty of guys you can choose from. Don't push yourself. ] 
(Lilli)[It's a pity. But I already have someone in mind. Thanks for your concern though. ] 
A while after that, while I'm busy shopping at the Guild, a doppel ran over to tell me something.
(Lilli)[What's happening?] 
(Anna's doppel)[An abnormal situation inside the Dungeon has occurred. Please return immediately. ] 
(Lilli)[Got it. ] 
I turn around and immediately return to the Dungeon.
From what I've heard, control of the Dungeon is being lost.
Judging from the situation, we guess that this is the work of an adventurer who invaded the Dungeon.
On my way through I confirm adventurers who are invading and without any exception... I kill them all.
All at once, I killed all the adventurers I could find.... Some with whom I was acquainted.
There were also some rookies too.
I killed them all.
It's natural. Our important place can't become tainted.
But, the Dungeon's control is still gradually disappearing.
(Lilli)[...... This is going nowhere. Gather everyone to the entrance to the 48th floor. The one below that is the control room. We are already unlikely to be in time for the 45th and 46th. Is it okay, Dullahan-san?] 
Dullahan, who is my long time friend and also has a father-like presence for me, showed his agreement with a swing of his sword.
(Lilli)[Yosh, everyone wait at the entrance of the stairs and we'lly kill the adventurers who are coming!! ] 
[[[Ooo!! ] ] ] 
And just as we had expected, the adventurers who seemed to be the cause came down.
In the same moment they came down, I couldn't see the Dungeon's MAP display anymore....These guys!
(Seraria)[Well, it seems good for a last bit of exercise. ] 
(Kaya)[... Step back Yuki. ] 
(Yuki)[Eh? Eh? Isn't it normal for the man to be at the front?] 
(Seraria)[Do you want me to pull you back with a choker?] 
(Lutz)[... Hey wait a minute. Seraria, you want to attach a collar and do a collar play?] 
(Lulu)[... But it might be good. Danna-sama wearing a collar... Haa!] 13)
(Yuki)[Stop it!? I don't have such a hobby!?] 
The monsters weren't able to match them even while half of them were having such a frivolous chat.
While conversing leisurely, the monsters that were almost lvl 100 fell one after the other, without exception.
While I am distressed, Dullahan jumps out.
(Yuki)[Oi, that Dullahan is extraordinary!! His level is over 300!! ] 
Such weak reactions.
For awhile now, I've had the feeling that they were n.o.bility, but to cut them down will be difficult.
I also chase after Dullahan.....
(Seraria)[Lately I have been training on par with Delille. With such a small difference in level I won't be stopped. ] 
The words came from the silver-haired beauty. There's a sound. Then a mysterious sword returns to its scabbard. 17)
(Lilli)[Ah,ahhh!! ] 
Dullahan-san is... gone...... !?
I have to absolutely kill these guys!!
Sorry, Raie-sama, Anna-san.
I won't return... sorry.
Raie-sama, the family name you gave me.
...Thank you very much for giving to me the same family name as your sister.
It seems that the time has come for me to return this name to your house.
But, I would have preferred to keep smiling by your side.
(Lilli)[I will not allow you to defile this Dungeon any longer!! If you want to proceed any further, then you shall have to go through this Lilli*Le*Kossel!! ] 
This is my last roar.
I won't be able to win against the person who easily defeated Dullahan.
But still... Until the very end.
In that way, I clench my sword searching for an opening in my opponent.
[[[Le*Kossel!?] ] ] 
Suddenly my opponents tilt their head in surprise.
I wonder why?
