Because of arguments in the topics and elsewhere and yadda yadda, to avoid further confusion, I am making this topic so we can reference waifus at any time.
1.) First come, first serve. No one waifu can be claimed multiple times. If someone has your waifu you want, pick another unless you strike a deal with the original owner of said waifu.
2.) No more than one waifu per person
3.) Waifu can be from any form of media
4.) Canon sexuality/preference of waifu does not apply here
5.) butts is a good rule
To get things started, obviously Mai Waifu is Kallen from Code Geass. So nyeh.
Maybe I should keep a nice list up here. Alphabetical by character or owner? Which would you prefer?
