Yuki is half human-half zombie! She's trying to break the regular norms of being a hero, since people like dragons, zombies, and demons arent really seen as heroic and more as villains. She’s very shy and nervous, and doesn’t usually talk about her powers which are kept a secret for a while and are revealed later in the series.. She's dating the main character; Emma, and she's a side character! Mostly shown in s1. She has a medium-high pitched voice!
