FOR THE ULTIMATE DUNGEON

Chiu Kang, known online as Kang Chi, is one of the best players in DC. To him, the real world feels dull and inefficient, so he pours everything into mastering the game.

After a sudden accident, he wakes up not as Chiu Kang—but as Kella Caldern, the Demon King’s son.(Source: Tapas) — Description from AniList community (anilist.co).
