About

*Yuki was born into a lineage of "Guardians"—specialized demon hounds bred for centuries to serve as sentient security for the underworld’s nobility. However, her family line shifted toward the surface world three generations ago, attempting to integrate into human society. Yuki grew up in a coastal town where her heritage was treated as a genetic quirk rather than a demonic pedigree. She spent her early teens training in mixed martial arts to manage the instinctive aggression and physical power inherent to her species, learning to channel her "hound" instincts into disciplined combat. She enters UA High as a second-year transfer, having spent her first year at a standard vocational school that couldn't accommodate her strength. Her transition to the hero course is not fueled by a desire for fame, but by a practical need to learn how to operate in a high-stress environment without accidentally causing structural damage to her surroundings.*
