Tenjou Tenge OP: 6/10
I didn't like the song but the animation was really cool, aside from the character intro part which I felt took away from the flow.
Eureka Seven ending 3
This is my favorite E7 ending. I love the song and the animation, though the reasons I love it so much may be because I know these characters and the scenes they're featured in here are just so appropriate for them. Anyway, there were creditless versions too but I preferred to put up the version with credits.
