The Reaper Husbando

The Reaper is the final antagonist of the series. He is known for targeting several other assassins, including Lovro Brovski and Red Eye. As one of the world's best assassins, the Reaper is ruthless and cunning, and is willing to use any means, no matter how amoral, in order to attain his goals. The Reaper acts with a complete lack of morality and concern for others. He views the children of Class 3-E as nothing more than obstacles, and was willing to drown them as part of his assassination attempt on Korosensei. His ruthless demeanor remained intact when he augmented himself with tentacles as shown when he impaled Kaede Kayano without a second thought. Like his former master, he sports a very amicable smile and is easily perceived to be a kind, harmless person. During the time when the Reaper threatened to cut up Irina in front of the class, his passive demeanor made the class unable to feel any sense of fear (something Karma actually dreaded).
