topic #4537, topic #7682, topic #4195, topic #8162.
Resubmitting from topic #7682 since it seems silly to avoid using their real names. It's been a decade, they aren't super-spoilery to begin with, and these are the names used on other sites like MAL and the Angel Beats! wiki.
Two of the names are already taken by two characters with few posts, so I included two renames for them.
