Ahem.

Wraiths are the demons of Episode 12. Just called Wraiths since I'm sucker for the english dub. Anyways, the wraiths in this universe are different than the one in Episode 12. Wraiths are simly put, the amount of despair from a magical boy personified. What happens to the magical boy? Who knows...

Basically summed up in this paragraph. 

"So wait, what you're tellin' me is that now instead of magical girls going absolutely ballistic and witching out, cuz some dumbass goddess bitch decided to rewrite the laws of the damn universe, you incubators finally decided to get off your lazy asses and search out for magical guys, who involved Hitler and the Greek Gods. Also instead of girls turnin' to witches, we guys turn into wraiths after our soul gems can't be purified no more!? That's so freakin' absurd! H-hey? Wh-what's.... Argh!" 

Anyways, Grief Cubes are the equalivent of Grief Seeds. However, their abundancy are a bit more common but their usage is limited. Basically, there are more but can't fully purify a tainted soul gem. Puella Magi are called Puer Magi since Puella means girl so Puer means boy. However, the general term I go by is Magical Fighter.

Anyways, Lenon go ahead an post but don't kill the wraith. Lemme get outta school and edit the stuff.
