Yomi is a well mannered individual who shows deep compassion for those of less fortunate backgrounds like herself. Despite her pleasant demeanor, there is a significant gap between her polite tone of voice and what she's actually saying, as she's known for savage verbal abuse; her refined demeanor masks her aggressive and unpredictable side. She came from the slums and harbors both great hate and envy for prosperous houses/families. She deems those born with a "silver spoon in their mouths" as fragile people who don't know the true hardship and suffering of the less fortunate. Be that as it may, Yomi is seen to be quite pretentious. Despite this, Yomi has a very motherly persona when it comes to taking care of the needs of her comrades. She likes to cook and clean, as well as tend to them if injured. She feels as though her comrades are family and shares a deep connection with all of them. She is 16.
