Uragiri wa Boku no Namae wo Shitteiru EP2 - Tune of Eternity

Yuki meets a man who introduces himself as Takashiro Giou, who claims to be his older brother and asks him to come with him to Tokyo. Yuki is initially confused by the sudden revelation and as a result (of the female Yuki accusing him of running away) causes his power to break the orphanages' windows. Later, he has a confrontation with Uzuki at school, and his powers almost goes berserk again. Frightened and confused at his growing powers, he runs away only to meet up with Zess who comforts him. As they begin walking, they are attacked by Duras or demons and are saved by Touko and Tsukumo, along with Takashiro who talks about the Giou Clan and how everyone of its members have special powers and that they need his power.
