Female character in Bible black for these reasons:
1. My chances of getting laid increase exponentially.
2. There's also a good chance that I get to keep my dick. Possibly even get a second one.
3. I'm much less likely to go crazy than the male characters.
4. There are no ugly females in Bible Black, so I'd automatically be hot and have a nice rack.
5. Soldiers in Elfen Lied are nothing but cannon fodder. Girls in Bible black often have a whole scene just for them.
