These are TTC's rules:
1. No Yandere's. Sorry, Yandere's but this is a place of Tsundere-ness!
2. Only Tsundere characters or characters who are family/friends of Tsundere characters are allowed.
3. Don't get too inappropriate. So no.
4. A contest needs at least 4 people entered to actually happen.
5. Keep bad language to a minimum. Baka is ok. Idiot, moron, stupid, all ok. But nothing above that.
