Soul Eater is another anime which handles diversity very well. Kilik is a Meister working under Death to reap souls in the latter's stead. He is a contemporary of the main characters of the show and makes regular appearances along with the main cast.
Kilik is in no way lacking as compared to Maka, Soul, Black Star and Death the Kid. Armed with fire and thunder, he can hold his own against the agents of insanity.
