Aegis Vol. 04 (Yaoi GN)

Izare often offends his squad, but Jino, his former foster brother, continues to defend him. But not even Jino can tolerate Izare's behavior anymore when he finds out that Izare killed their beloved sis - although he doesn't know that Izare killed her in accordance with her own wishes. Jino removes the chip embedded in him and successfully runs away from their base without Izare. He takes a job at a small downtrodden restaurant where everyone thinks he's just a meek, weak little boy. But Jino suffers from insomnia, and still can't get Izare off his mind.
