History
Eiichiro Saiyama is a manga artist who is simply lonely in school, until one day when he was drawing, a girl approached him and told him that he was drawing. very well, and she asked him if he planned to become a manga artist, he liked this very much, and he was very happy that someone praised him, this made him continue drawing and later become a manga artist.
One day he received a package where Takumi was, and he was very surprised, then Takumi began to investigate his room while praising his manga a little before opening a door to Eiichiro's room, where multiple murdered people could be observed.
Eiichiro tried to excuse himself by saying that this room was used by his assistant, but when cornered, he shows his true personality, explaining in a completely erratic way, that he doesn't know what it feels like to work so much on a manga, and not be not at all praised for his work, showing that he only wants to be praised (while doing so he stabs one of the corpses multiple times in its mouth with a paintbrush) while saying that he did all that to improve on his sleeves and be praised even more.
At that moment, after a few words between them (where Takumi marked his kill with 20 points, and his Manga 55 points, saying some good things and some bad things about it, which even though at first Eiichiro seemed to like it saying "thank you for your criticism dear fan" but quickly going back to how he was saying that he didn't need fans who didn't really praise him, and saying that he will return to Takumi in his next reference doll), when Eiichiro tried to attack him, Takumi killed him on the same way that Mukuro Ikusaba died ending him once and for all.
