Hundred

Hundred is a twelve-episode action anime that premiered in spring 2016. The series blends mecha, science fiction, and ecchi elements into a story about humanity's defense against alien invaders called Savages. The only effective weapon against these creatures is the Hundred, a powerful combat device that skilled warriors called Slayers learn to master at military academies.

The protagonist Hayato Kisaragi enrolls in Little Garden, a prestigious academy city built on a naval ship, to train as a Slayer and join the fight against the Savage threat. His first days prove eventful when his roommate Emil reveals an inexplicable familiarity with him, and the school's reigning champion Slayer, Claire Harvey, immediately challenges him to a duel. These encounters hint at mysteries buried in Hayato's past that begin to surface as the series progresses.

The finished series combines school-based training sequences with larger conflicts against extraterrestrial enemies, appealing to fans of action-heavy sci-fi anime with a competitive academic setting. Hundred completed its broadcast run without continuation, making it a self-contained story for viewers seeking a complete narrative arc.
