She’s known for her energetic and mischievous vibe, claiming herself as the "July Summer Devil."

Yuko loves playing and socializing, often encouraging others to join her in games like beach volleyball.

Yuko is a first-year student in Class 1-1 at Infinite Stratos Academy.

In the sports festival cosplay outfit change race, Yuko was originally supposed to help Charlotte Dunois change but left a note and ran away, passing the responsibility to Riko.

"Let’s play beach volleyball!"
