Who decided to give them the A/B names in the first place? Seems kind of confusing to me. ^^;;

Spoiler for Chaos Head routes:

You just get a regular bad end (straight back to the title) if you give the wrong answer on top of the O-FRONT building.

Personally, I liked the B route ending the best. The A ending depressed me more for some reason... maybe because in the B route, dying really is the best choice, whereas the AA end shows that there's no real need to die in the A end.
