The blurb is tentative. I'll revise it once I start writing.
In his previous life, after watching that person die young with regrets, he made a deal with a god, giving his own extraordinary talent to a boy named Kita Shinsuke.
Irie Nagata was left with nothing.
During Kita Shinsuke's third year of high school, a sickly delinquent transferred to Inarizaki and declared that he wanted to join the volleyball team, despite his frail body.
At first, Kita Shinsuke only thought of him as a junior with great skill but poor health. It wasn't until the day he met the god that he learned he had been an "ordinary person" all along.
A sickly, delinquent junior who has a secret crush (a volleyball idiot who doesn't realize he's in love) & reliable, gentle senior Kita
Theme: There is a god three feet above your head.
