Takatoo Keisuke♂

A solemn young man who is trying his hardest to maintain a happy, average life in order to hide his deeply sadistic side. While he has a kind of a stoic nature on the outside, inside he is filled with conflicting and dark emotions, his passion for abuse and torture that bring him inescapable shame as well as pleasure. If it weren't for these hidden desires of his, he'd be considered just another unlucky and unfortunate victim of the Game. But despite having a hard battle to subdue these inner feelings, he is still giving his best in order to protect and save all of his loved ones before anything else. Nemu perfectly describes him as “an odd man, excited to watch girls tortured yet trying to save the very same girls from death, even at the cost of his life”. The Game will serve as a perfect test to his mental strength and endurance. A choice on whether he will let himself succumb to his inner beastly desires or whether he will persevere long enough to find a way out of this hellish nightmare shall be left to no one else but him to decide.
