Eiichi is the Ultimate Gacha Game Player.

Eiichi is a kind and sweet individual who's a master of all gacha games- he plays all sorts of Gacha games from Gacha RPGs to rhythm gachas. He loves the rush he gets when he pulls units and tries his best to help others feel the same rush. He works part time at a gym to fund his gacha addiction and he finds it hard to hold back on the spending when a seasonal unit appears. He tries his best to practice self restraint, though. He's always encouraging others to work on bettering themselves with dealing with their bad habits.

NOTE: The Gacha his character refers to is NOT gacha life or gacha club, his talent and actions refer to the mobile game genre that originates from japan called Gacha which is defined by spending in game currency to play a lottery to get new characters or gear.
