## Plot

Yuu looks for Nagi and for when he sees him he thinks he’s made an interesting discovery. He later goes into the alley where Nagi is found injured and says that he is there to help him and acts surprised to see the injuries of Nagi, he heals him and chuckles saying that it’s their secret how he healed him. And says that he couldn’t help himself when he saw his ripped clothes and says that they can talk anytime. When Yuu sees that Nagi can "control” his shadow he thinks it’s time for step two. After a while he meet Tobi in the same roof, meanwhile Tobi asks roundabout questions he cuts to the chase and starts a fight. When Yuu is healing from Tobi’s attack on an abandoned building he is a bit stunned, and thinks to himself “To think I’d meet someone if the same “odd type”" as he hasn’t meet such a skilled user in a long time. Yuu sees Nagi beaten up and becomes his mentor, but Nagi is unconscious and leaves him in his room. He later teaches him how to use his shadow, and when he is ready he pierces Nagi's shadow. After that he fights against Tobi, later on when their fight is done Yuu talks to Rei about something, stating that they have "met before in an accident", leaving that as his final words, he uses the ability "Gates of Hell" before he passes, leaving an explosion behind.

After the explosion Yuu infests Nagi. In the hospital, when Ryou wants to take a photo of him, he wakes up, startling him. Then Yuu says that he won't harm Ryou and offers to teach him how to use his power, in exchange for a single request. When Ryou brings Q-ta in the camera and asks what he should do with him, Yuu asks him to keep Q-ta the way he is. Then Yuu asks Ryou why he is using his shadow to earn money, Ryou replies that a family member is ill and therefore he needs money. Yuu suddenly thinks about his sibling.

In chapters 28 and 29, Yuu, who has infested Ryou, attacks Mai and the "Agents" secret base and collides with a combat unit, but easily copes with one of them. He then changes his form into that of Ryou and uses his shadow to render unit members unable to move. After devouring their shadows, he breaks into the reference room. When he sees investigation file on Yukito Mutsuki he comes to his house.
