Takeru Yagi

Takeru Yagi has lived with the Touma family since losing his parents and was raised by household head Touma Rokunosuke. His everyday life includes his kendo-club best friend and rival Yamato Takeshi, the Shiratori sisters, and childhood friend Oosu Seri. Everything changes when an earthquake strikes the school and Takeru wakes to find it ruined, seemingly abandoned for centuries, with the teachers and students gone.
