In the world of the brutally difficult mobile gacha game Pick Me Up, 1-star heroes are nothing more than fodder—disposable tools used to learn a boss’s attack patterns before being discarded. That was the cold philosophy of Seojin Han, the world’s fifth-ranked master known as "Loki."

But everything changes when Loki loses consciousness while attempting to clear an impossible dungeon. When he wakes up, the master has become the servant. He has been transported into the very game he once ruled, now trapped in the body of a lowly 1-star hero named Han Islat.

Stripped of his rank and forced into the digital flesh of a character he once would have sacrificed without a second thought, Han Islat must now survive the meat-grinder of the game's 100 floors. To return to Earth, he must lead a group of novice masters and heroes through a world where a single mistake means permanent deletion.

"You messed with the wrong person."

This is the story of a Master who refuses to lose. Can a gacha character rise through the ranks, defy the odds, and eventually defeat the "gods" pulling the strings from the other side of the screen?
