Eiichi is a kind and sweet individual who's a master of 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 that 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 restrain, however. He's always encouraging others to work on bettering themselves.
