She is the captain of the budding MMA club, which at the beginning of the series had only two members and no adviser. She is constantly advertising the club and recruiting anyone who will join, even going so far as to challenge Natsuo to a fight, where both girls fought evenly but had to be broken up by Sanae's unexpected arrival. On their second sparring session (where Natsuo intended to lose), Yuzuko, having fought Natsuo beforehand, now knows what to do this time around, and proceeded to seal Natsuo's movements by pinning her to the ground, winning the match. This spurns Natsuo more than ever, having finally met someone with the capacity to defeat her.
