MapleStory is turning Multi-gender.

In all seriousness, there are already people trying to make traps in Maplestory. This just helps them out. I'm still wondering if we'll be getting these hairs in GMS, and if so, will they stay female only?

Probably not, K-ON would have to be in english first, this is part of the K-ON tieup, in which nexon japan is probably paying them a shitload of money for the rights to do this.
