Heimdall  

Higashiyama Kazumi, 東山和実

Heimdall was sent by Odin to kill Loki and took the form of a young boy named Kazumi Higashiyama as a disguise. However, due to losing his right eye, he had to wear purple hair that covered half of his face and long sharp claws which required gloves to hide them. He believed Loki was responsible for stealing his eye and intended to retrieve it or avenge its loss. Despite being serious, Heimdall is often the target of jokes due to his obsession with Loki and serious personality. In the manga, he attends piano lessons, singing lessons, and cram school despite not attending school. In the anime, he gets dragged along on shopping sprees by Freyr, much to his dismay.
