Episode Title:
A World That Does Not Exist Here.
Episode Description:
At the Zhiend concert with Nao, Yuu feels a familiar sensation upon hearing what is supposed to be a brand-new song. He experiences a sudden flashback, in which he and Ayumi lived in a research institution in another parallel timeline where they were monitored for their abilities. When Ayumi's collapse ability caused damage to the structure, a scientist named Tsutsumiuchi helped Yuu escape and urged him to use his true ability of plundering other people's powers. Yuu eventually reached his brother, Shunsuke Otosaka, who possesses the ability to time travel. Back in the present, Yuu regains consciousness, now aware of the fact that he has a brother. Yuu and Nao are then approached by Kumagami, who takes them to a secret underground haven to meet with Shunsuke.
