Description
Yusa belongs to the prestigious Ice Tribe, a high-level demon group revered in the demon world. This ice devil possesses a human equivalent age of roughly 15 years. Her striking appearance features long crystal blue hair, sparkling blue eyes, and embodies the traditionally gentle snow woman aesthetic. She typically wears a light blue kimono that conceals her curvy figure, standing 162 cm tall. A deeply embarrassing aspect of her past is her childhood resemblance to a small mole, a trait provoking strong reactions if referenced; her birthday is February 22.

Her personality is generally polite and mild-mannered, yet shifts noticeably when facing disrespect toward her family name or younger sister. She demonstrates fierce protectiveness over her younger brother, Kōji, reacting with visible disdain or anger toward his bullies. While fundamentally kind and elegant, she experiences jealousy when feeling ignored or underrepresented, occasionally leading her to form attention-seeking alliances like the "Rebel Alliance" with Mei Tachibana against main characters. She also exhibits occasional air-headedness, particularly in devising unconventional business ideas.

Yusa wields ice-based abilities for both practical and commercial purposes, manipulating ice and cold air to generate snow indoors or freeze targets with her breath, while remaining immune to her own freezing effects. She leverages these powers for entrepreneurial ventures like crafting shaved ice or ice cream. Her professional drive focuses on succeeding in both the demon and human worlds; she runs businesses in the demon realm and co-manages the human-world bar "Eclipse" alongside Kōji. Her ventures face challenges, like selling cold treats in the naturally cold demon environment or pricing dangerous ice cream exorbitantly.

Her core relationships center on familial bonds and interpersonal conflicts. She acts as Kōji's primary guardian, sheltering him from harassment while tolerating his unique physiological traits. She dislikes Jashin-chan due to persistent bullying of Kōji but maintains kindness toward Pekola and other allies. Yurine Hanazono earns her respect for treating both her and Kōji well. Narrative developments highlight her ongoing struggle for relevance, including attention-seeking collaborations and reactive anger toward childhood appearance mockery. Her participation in conflicts, like the "Waki Aiai Sabatsu Battle" game where she combines ice attacks with Kōji, underscores her integration into broader conflicts despite occasional feelings of exclusion.
