Tokaku Azuma

Tokaku Azuma (東 兎角; Azuma Tokaku) is the primary main protagonist of the manga and anime series Akuma no Riddle. She is a former student of the 10th year's Black Class at Myōjō Academy, registered in a competition to try to kill Haru Ichinose, with the reward to be anything one could wish for.

However, when she was first told about her mission, Tokaku decided she did not want a reward and was going to protect Haru from the other 11 assassins.

During Isuke Inukai's attack on Haru, it is revealed that Tokaku has never killed anyone before, despite possessing very useful skills as an assassin. She is a distant and cold girl, who dislikes when people comes too close to her and she especially hates it when people call her by her first name, with the exception of Haru. However, she eventually grows to care for Haru over time.
