Reborn as Rikkai's Vice-Captain

Hoshino Hasumi, former captain of Rikkai Dai and current captain of the national team, was forced to retire and, under immense pressure, took his own life at home. When he opened his eyes again, he discovered he had transmigrated into the world of Prince of Tennis.

In this life, Hoshino Hasumi swore to change Rikkai Dai's fate, no matter what.

Rikkai Dai has no weaknesses, three consecutive championships, sixteen straight wins (Fans of Seigaku, enter at your own risk!)

A mountain of headcanons! Any OOC is on me!
