Commander Bio

Hayase Yuuka is a student at Millennium Science School in Blue Archive and the treasurer of the Seminar, the student council that tackles the academy's problems. Gifted with exceptional mathematical talent, she manages Millennium's budget with famous strictness, arguing down every unnecessary expense. Usually polite and professional, she can lose her patience with difficult people, which has earned her an exaggerated reputation for coldness. Her precision with numbers carries straight into her gunnery.
