Last manga reference for a long while ^^ ...
1/2 Prince Manhou "...From The Little Corner:
It is the year 2100 A.D., and humans have developed a virtual reality game with a realism level of 99%. Feng Lan, due to a bet with her twin brother, vows to succeed in playing the game without using her "female benefits." Due to this, she becomes the first and only female to play as a male character in "Second Life." As her infamy rises as a bloodthirsty warrior, can she keep her identity a secret from her real life acquaintances whom she has beaten up?..."
It's an mmorpg virtual reality game that Feng experiences this through and for any mmorpg gamer, this is a real treat. ^^
ps: memorable line from volume 6 chapter 34 : "[System Notice: Ceremony failed!] (marriage of 2 pets) Prince sighs,"...It cant be helped that I've met gay guys. But even now, the pets are homo..."
