Kou Mitsuki

Mitsuki Kou is an elite and widely feared gamer known online as "Headhunter Crim." His legendary skills in player-versus-player (PvP) combat have made him a living legend in the gaming world. His life takes a sharp turn when he's invited by his own father, a game developer, to test the revolutionary new VRMMO, Destiny Unchain Online.

Upon logging in, Kou finds himself trapped. Not only is he unable to log out, but his avatar has been forcibly changed into that of a young vampire girl from the rare "Crimson Noble" race. Stranded in a dangerous, isolated area due to a bug, he must rely on his veteran gaming expertise to survive. Adopting his old handle, Crim, he begins to adapt to his new body and powerful abilities, all while seeking to uncover the game's secrets and the true intentions behind his father's actions. His journey marks the beginning of a new legend: that of the fearsome "Crimson Demon Queen."
