Destiny Unchain Online: Kyuuketsuki Shoujo to Natte, Yagate "Aka no Maou" to Yobareru you ni Narimashita

Kou Mitsuki is such a feared PVP gamer that he's earned the nickname "Crim the Headhunter" in some circles. His next game to take over? "Destiny Unchain Online," a brand new VRMMO game developed by none other than Kou's father. But, no new game on release day is without its bugs—namely, Kou glitches to the middle of nowhere, and his vampire avatar is turned into a girl!

Is there a mystery in this game? No matter, gather your friends and aim for the top!!
