Rosario + Vampire (Seasons 1–2)

Rosario + Vampire (ロザリオとバンパイア, 2008) is a Japanese anime series you can watch online on iFILM. Studio Gonzo adapted Ikei Akihisa's manga about an ordinary teenager, Tsukune Aono, who ends up at Yokai Academy — the only school that would accept him after he bombed every entrance exam.

The catch: Tsukune is human, and humans are very much not welcome. Half his classmates can smell it. The school rules forbid revealing your monster form in public, which gives him just enough cover to survive — as long as vampire Moka Akashiya keeps biting his neck before anyone else does. Over time he picks up a whole crew of protectors: a succubus, a snow fairy, a witch, each with her own reasons for befriending the one human on campus. Leading voice cast includes Daisuke Kishio and Nana Mizuki.

The show works best when it stops pretending to be a harem comedy and leans into the threat — every moment Tsukune is close to exposure has real stakes. Stream Rosario + Vampire (2008) online on iFILM.
