Soul Eater's first opening! :D The one opening I wont skip through when watching an episode. The song is really catchy and it's just really fun to watch! ^ ^
There are hella' lots that I like and I couldn't choose one. Maybe the best I've seen right now is Attack on Titan opening but I'll post this instead....
I do 爱情 Change (Bleach) Unreal Paradise (Kampfer) Dragon Soul (DBZ Kai) and 颜色 (Code Geass..) Also a lot more. But i like the Youko x Boku ss (Inu x Boku ss) opening.
