Ryen was confused as to how such an Island could be made primarily of metal . The name of Ironfort was not undeserved . Just like Kaguya , Ryen was also thinking that the metal and ores found on the Island could be of much use to the crew . Indeed , however , in order to get into the Giant Pirate ' s base , two options presented themselves to the pair of pirates . Either stealth or diplomacy . Ryen We could talk to th . Kaguya Ryen , our first objective is to obtain information about the division commander here . The ninja guard will be on the lookout as well but they will be busy with other things mostly , meaning its up to you and me . Ryen shut his mouth and looked disappointed . Stealth missions were tiring and unnecessarily difficult . He sighed and obeyed his Captain ' s instructions . She pointed towards the mountains and although Ryen wasn ' t necessarily listening to everything , he got the general message . He turned his body into smoke and began carrying Kaguya up into the mountains . Ryen Here we are , almost there . Although his captain was in a man ' s body , Ryen found it embarrassing , especially in his elemental form , to be grabbing his female captain in such a manner . Although she couldn ' t tell , he blushed awkwardly , before shaking his head and concentrating on the mission ahead of him . The thing about Ryen ' s powers is that even though he disliked stealth , he was perfect for it . Made of smoke , he could get almost anywhere , through gates , ventilation shafts , sewage gates , gas chambers . Ryen sighed sadly . Ryen Go on captain , sneak into the base . I ' ll catch up to you in a second . I just want to check some stuff out . From under his coat , he took out a pair of binoculars that the ninja clan had given to him , and looked at the pirate ' s base . Since everything was gray , it was hard to make out the layout , but he got the gyst of it . The headquarters were in the center , and everything else was basically layer after layer of defense organized in a circle around it .
