Well, Slayers, much like AA, tends to go back and forth between the absolutely silly/ridiculous and very serious.

Lina is a (very) wee lass of fifteen who spends her time wandering around looking for adventure, food, and profit but keeps falling into situations where she has to put her wants aside and save the world. Here in the tower she is bound and determined to find a way to blow it the hell up because seriously screw this place and its stupid admins that have done nothing but make her life hell.

If you don't mind something backdated, there's this bit where she's going around and magically graffiti-ing that message all over the place as an option.
