Tsubasa anime. You know there's something wrong when the music to an anime overpowers the actual story. In addition, the music (to me) seems to be quite jarring. Trying to enjoy the series is damn hard when the music drives me up the wall. This of course can also mean that the anime is rather bland, which I have to say is quite true (though I did squee when Touya appeared, and went slightly spastic when ASHURA was shown.) Oh, and the seiyuu confuses me mainly because I keep on expecting someone else to be speaking from Sakura, Syaoran, and Yukito (love Touya).
Trinity Blood. My honest opinion: Equilibrium meets Hellsing meets Trigun. Hellsing because of the vampires and the main Hero's power up (40% power level, etc.) kick your normal vampire arse). Equilibrium because d00d! Tres is so doing the GunKata (and omfg! I fangirl over Tres, it is his damn character design and his guns). Trigun because of the alien/space ship/mad-psycho relative (probable relative I'm guessing here), and how our main hero might be one of the space travelers. So, in conclusion I need more of this series before I can make a proper judgment on it.
Back to maths.
[EDIT: No wonder the music to 'Tsubasa' irritate me. It is done by the same people who did the music to Hack Sign. Urk, hated the series and music with a passion. Techno is NOT suitable for 'Tsubasa'.]
