I reeeeeeaaaaally like this manga so far! It's about this 19 year old girl who plays virtual reality game called Second Life. She makes a bet with her twin brother that she can make I through the game and all without people helping her (because she's a girl). So she becomes a masculine version if herself. Gender switching is actually banned, but the creators let her because she was the very first person to enter the game. so she became a (dazzlingly hot) male bishie. Now she has the obsessive girls to worry about though... But with game names know one knows who she really is, and she runs into her brother briefly at one point (he didn't recognize her). It's pretty humorous since only the reader goes about knowing that he (named Prince) is actually a girl.
