Hifumi Yamada
Hifumi Yamada is the Ultimate Otaku and as the title suggests, he is obsessed with anime and claims to be only into 2D girls rather than 3D girls, which he constantly reminds the player but his actions throughout the game suggests otherwise. He comes across as creepy and perverted as he constantly makes suggestive remarks that creep out the other characters, including Leon which points it out. He also make a lot of anime remarks in his dialogue. Throughout the game, he is extremely loyal to Celeste which he threats like a princess, though she is incredibly hostile towards him. He gets a crush on Alter Ego as she "actually listens" and is not creeped out by his hobbies. This led to a conflict between Ishimaru and himself and this leads to Celeste manipulating Hifumi into becoming her accomplice as she steals Alter Ego and claims that Ishimaru forced her to do it for him as neither Ishimaru or Hifumi was allowed to get close to Alter Ego at the time. This leads to Hifumi helping Celeste kill Ishimaru, plot to frame Hagakure and cause a problem involving a moving corpse. After the plan was believed to be a success, Celeste killed him as well and with his last breath, he managed to remember everything and call out his murderers name, Yasuhiro, which was both Celeste's real name and Yasuhiro Hagakure's name.
