Teito Klein is a former slave who attends the Barsburg Empire's military academy. Having no memory of his past and the power to wield a rare ability called Zaiphon, Teito is constantly under the scrutiny of his peers - except for his best friend Mikage, the only person he connects with.

Both of these anime revolve around the struggle between light and dark, and take place mainly in a cathedral setting. With some beautiful animation and intriguing character interaction, the animes are very enjoyable.

Alucard is a vampire who works for Hellsing – an organization responsible for hunting down and destroying other vampires. In these dark times, whoever is bitten by a vampire turns into a ghoul -- with the exception of Seras Victoria, Alucard’s newly created and appointed apprentice. Now, Seras must serve her master, Alucard and work for Integra Wingates Hellsing. Nefarious vampire activities are being reported throughout England, and it all traces back to the organization named “Millennium”. Will the Hellsing organization, under the command of Sir Integra Wingates Hellsing, be able to prevent a full scale war? Or will the world become a battlefield of destruction?
Vampires. The Vatican. Violence. Vendettas. Get it yet? Also: big guns, secret orders, betrayal. Both series have it all. Trinity Blood is the more innocent of the two animes, with more laughs and less gore, and the style is more normal vs. the over-the-top animation of Hellsing OVA. But they are both about the brittle balance (and the brutal fight) of good vs. evil, with morally ambiguous main characters and a wagonload of religious symbolism. If that gets you drooling, one or the other should suit your palate.
