Action Taimanin

 is a free-to-play 3D action role-playing gacha game developed and published by Gremory Games on mobile, and later ported to Windows PCs by Lilith and Infini-Brain.
Story.
Action Taimanin takes place in an alternative future of Japan. Demons have crossed over from the dark side, breaking the unspoken rules of non-interference. The rule is now obsolete, and a war rages between the humans and demons. As the fight rages on, crime syndicates are taking advantage of the chaos to rise in power. The government established an organization of ninja called "Taimanins" to fight the demons.
Gameplay.
Action Taimanin features multiple game modes. The main quest begins with retrieving a stolen bio-weapon from a "UFS" base. Time Attack mode has players racing against the clock and other players to try and rank as high as possible. Special Mode is a vehicle race to avoid obstacles and get to the finish line.
By completing different modes and training, players can unlock additional outfits for their favorite characters. Support characters are also on hand to help out with various skills. Bonding with the support characters will, unlock special slice-of-life events.
Development.
Action Taimanin was announced at TGS 2019 as an all-ages 3D game set in the Taimanin universe. The starting playable characters unveiled were Igawa Asagi, Igawa Sakura, and Mizuki Yukikaze.
Release.
Shortly after the Japanese release, users noticed a remixed version of Au5's "Snowblind" was used in-game but the artist wasn't featured in the game's credits. Gremory Games would then issue an apology for copyright infringement and take measures to avoid similar situations in the future.
In June 2020, it was announced that the role of Igawa Asagi would be recast with Sayumi Watabe replacing Ami Koshimizu.
In September 2020, it was announced that Action Taimanin would be released globally for PC on Steam, as well as on iOS and Android devices.
On May 4th 2021, the Japanese and global server merged with the former folding into the latter. The Japanese server final closure will take place on July 27th.
Reception.
"Sequential Planet" complimented the game's visuals and performance as well as it being F2P-friendly. However, they criticized the stamina system, combat, and enemy variety. Iyane Agossah from DualShockers included Action Taimanin in his top 10 games of 2020, praising the game's story and calling it "surprisingly good and researched". However, he criticized the aggressive monetization and repetitive gameplay.
