So depends- Okay but really Kokichi as a top mainly in the relationship  between them. Lets be honest, Shuichi can't really top unless its pregame but even then he likes seeing his shy boyfriend be dominant.

Survive in the purge? Well if I knew that it was happening I'd get a tactical shovel and run into the woods, it has a million and one uses. But if I didn't know, it'd try my best to hide in places no one would think about.

Ooooh this is interesting. So here the ranking for boy and girl characters.

Trigger Happy Havoc -  Chihiro and Celestia
Goodbye Despair -  Nagito and Sonia
Ultra Despair Girls -  Servant and Toko
Killing Harmony -  Kokichi and Miu
