As long as Tenya can remember, Kiyoto—his younger cousin by a year was always with him and his family since her father was a pro hero and could not be there for her so, she was often at his house.. it wasn’t weird since she had been there since she was an infant and Tenya was like the big brother as never had—he was like Tensei for Kiyoto. Tenya always took her gentle heart and quiet demeanor into consideration and when she had gotten her quirk he was there to help her!
