You can keep it from going into girl only and male only forms by not attacking it when it says it's changing. Wait a turn or two and it will stay in the original form!

I wanna try playing Allen with other Xenosaga players because I wanna see what they think of my Allen. He's so beautifully fail, and I'm normally good at that NPC that is so horribly normal that he's fail compared to the heroes.

That was what I meant. The username. *fail*
