...I kinda wish I'd saved that chatlog from the channel, actually. We talked about that a while ago, and almost had the entire cast list down....
I remember some of the stuff. For example,
Earth: Tenshi, and I think there were some other people.
Fire: Mokou
Wind: Aya
Water: Nitori/Letty/Cirno
Heart: Satori/Koishi/Marisa/Fanon Alice
Captain Planet: Patchouli or Reimu
Gaia: Yukari
You know you're addicted to Captain planet when you were the one who started the Captain Planet Visual Novel.
