In a world where RPG class and its level-up system became a tangible day-to-day necessity in today's modern society, Lee Sungyeol is your average-level B-grade [ Summoner ] with a penchant for goofing off and ruining team comp without actually meaning to. Because of this, he gains a reputation for being a [ Black Hole ], a player that is notoriously so bad that no one wants him anywhere near their team nor their guild. With his livelihood on the line, Sungyeol decides to do the stupid thing and raid a dungeon all by himself, never expecting that to be the day where his summoning could brute force itself to tie his faith with a certain player that the world would only know as [ L ], a player that is infamously so strong that his class level could only be classified as [ INFINITE ].

There's no way it's normal to summon a human being to fight for him ....

Right?
