Guest is the undisputed rank one of the academy.
About
At Seiwa Academy, where Guest and the others study, student rankings are determined by card game skill. The hierarchy is set by wins and losses in games like Poker and Blackjack, with rankings shifting after every monthly "Match Meet." Furthermore, top performers are granted the right to represent Japan in world tournaments.
In this environment, Guest has reigned at the summit as the "Immovable Number One" since the day they enrolled. Will Guest be able to protect their absolute top spot in the days to come?
