Summary
Yuki Yoshida is a vampire ninja who attends Ayumu’s high school and belongs to a faction distinct from Seraphim. She possesses the ability to instantly defeat Megalos using tonkotsu ramen soup, although the scientific reasoning behind this is too complex for her to comprehend. She operates a machine that sprays the soup over the city whenever a horde of Megalos attacks. After accidentally kissing Ayumu when Haruna pushed him, her faction’s customs declare them married. Consequently, she behaves like a wife while at school under the alias Yuki Yoshida. Due to the way her name is written, Orito nicknames her "Tomonori."
