In a bizarre fantasy world, students known as meisters are trained at the illustrious Shinigami Weapon Meister University; but the tools they wield are no ordinary weapons! Each meister is paired with a human-like being who can transform into a weapon at will; and after defeating a pre-kishin - a human whose soul has darkened - the weapon eats the soul within it. A meister's ultimate goal is to collect ninety-nine pre-kishin souls and one of a witch so that his or her partner will become an all-powerful Death Scythe. Maka and her partner Soul Eater; Assassin Black Star and his partner Demon Blade Tsubaki; and Shinigami's son Death the Kid and his partners the Demon Twin Pistol Thompson Sisters each vie for their ultimate goal, but plenty of challenges and adventures lie in their way!
Mahou Sensou rather is poor, and for some reason I keep drifting back to thinking about why soul eater is a million times better while struggling through this mess. Not that they share a lot in common other then the otherworldly air to it... i keep coming back to how soul eater does everything better then this show. (and i'm not even a fan of soul eater)
In a world where magic is a reality, the young Louise is at the bottom of her class. Dubbed "Zero" by her classmates at Tristein Academy (due to her zero success rate for magic), Louise (along with all first year students) was charged with summoning a familiar; and instead of a cute magical creature, the familiar arrived in the form of... Saito Hiraga, a normal Japanese boy who was abruptly teleported from his own world?! Can both Louise and Saito come to terms with their new and complicated "relationship" and (more importantly) help Saito find a way home?
In this "romantic comedy but sometime serious magical school story," life as Arata Kasuga knows it is wiped out by a bizarre incident known as "Collapse Phenomenon," which causes worldwide destruction and takes his cousin Hijiri Kasuga to the next world. To resolve the "Collapse Phenomenon" and bring back Hijiri, Arata enrolls in the Royal Biblia Academy. Waiting in the school are seven beautiful female magic users — the Trinity Seven.
Both shows are set in a magic school that is not in the ''regular'' world and both stories are based on something that could destroy the world. Both shows have multiple girls chasing the main character.
Trinity Seven is like a lvl 10 Mahou Sensou though. But if you like magic and magic academies, both shows have it.
