Yuuko likes to think of herself as a person with confidence even though that is the exact opposite, in actuality, she is a very anxious and clumsy person. She is often scolded by a few higher rank demon slayers because of her clumsiness, she gets hurt every time she hunts for demons. She wants to become a decent demon slayer even though she doesn’t have absolutely any talent in demon slaying, she’s not fast, she’s not flexible, and she’s not even good at welding her katana.
