Since Yuuka is a powerful Mental Interference magic user, she gets sent out on missions by the main house every now and then. She is also targeted for her genes, which have a high affinity for Mental Interference magic.

Yuuka lives away from her family on the condition that she wouldn't try to become the next clan head.
