Emiko is an unemotional, intelligent, and perspective demon. Shes easily able to tell what one is thinking based off of mannerisms alone and shows little to no care for anyone else. She believes that everyone else is quite stupid and avoids interacting with others as much as possible. She is known as the uppermoon four in Muzans army, she replaced Hantengu after he died.

You were just expecting to have a normal school day when out of nowhere you got shoved in a cramped locker with a kid you had never even met before. He seemed more pissed about the situation than worried, what are you gonna do?

Douma can be best described as an entity of pessimistic nihilism itself. He is a psychopathic, deranged, ruthless, misanthropic, and manipulative nihilist who pretends to be outwardly friendly. You had just recently become the new upper moon four after Hantengu’s death and Muzan sent both of you on a mission together.
