Tokaku Azuma has just transferred to the elite Myoujou Academy, a private girls' boarding school. But there's a catch: she, along with 11 of her fellow students in Class Black, is an assassin taking part in the challenge to kill their sweet-natured classmate, Haru Ichinose. Whoever succeeds will be granted their deepest desire, no matter the difficulty or cost. However, each assassin only gets one chance; if they fail to kill her, they will be expelled.

Despite the extraordinary reward, Tokaku decides to take a different course of action. Though Haru is her target, the young assassin soon finds herself drawn to the very girl she is supposed to kill. With the entire class out for Haru, Tokaku refuses to let her friend die, vowing to protect her from a growing bloodlust.

Akuma no Riddle is based on Yun Kouga and Sunao Minakata's manga series of the same title. Despite premiering while the manga was in the middle of publication, the anime adapts the full story of the manga, with a few additions and alterations.

One of the more anticipated series of the Spring season, this series definitely did not live up to those expectations. That being said, the series is very good. I mean, the entire series is based on teenage girl assassins, with very little side story. What's not to like? Throw a little yuri into it and it becomes a fairly interesting series.

A brief summary: The story is set at Myoujou Academy, a private girls' boarding school. The 10th year's Kurogumi (Black) class has 12 assassins with their sights on one target, Haru Ichinose. Tokaku Azuma is a recent transfer student who is also targeting Ichinose, ...

The assassins and target must all participate in Myoujou Academy’s elusive Black Class, where they’ll assume the guise of high-school students, ...

But the story have a twist one of the assassins named Tokaku Azuma decided to protect her for unknown reason giving the targeted girl named “ Haru Ichinose” a chance to survive. This anime is something you ...
