Time Traveler

Jikan Sokō (時間遡行)

A government committee reflects on Talented people upending the normal order of human society. The government tried to counter this threat with units of Talented individuals under their military's command, but those Talented soon turned on their masters as well. Talentless humans eventually managed to restore order, but at a heavy cost. In the present, the class notices Nanao's disappearance while Seiya freezes an entire lake. 

While Nana tries to gain more information on Seiya's talent, she finds another classmate, Yōhei Shibusawa, breaking up a fight with Moguo using a time travel talent. At lunch, she finds out more about Yōhei's talent: that he can only travel backwards in time to a certain extent. Suddenly, the two are interrupted by a suspicious Kyōya, as Nana tries to avoid implicating herself. Later, Nana gets Yōhei to demonstrate the limits of his talent, and her past self spots Yōhei before she carries out her assassination of Nanao. Late at night, Nana lures Yōhei to a spot where she claimed to see Nanao being eaten by an Enemy of Humanity. As he travels back about 24 hours in time, Yōhei ends up trapped in the river that Seiya froze previously that morning.
