History
Yui has been known to be killing people since she was young before she got hired by Bakuga Tsukikage to be a "student" of her Akatsuki Academy.

Akatsuki Strikes
Yui was first seen, along with her fellow Akatsuki academy members, going toward Hagun academy. She was the first to try and attack, taking on both Ayase and Yuuri and had some how defeated them both using an unknown ability, named Total Reflect.

Yui was then seen, with her fellow Akatsuki members, about to clash with the other Hagun academy students, however, Akatsuki academy was betrayed by Nagi who had concealed their movements and allowed the Hagun students to defeat them. However, Yui and the other's were revealed to be hiding in a different space.

After Ikki, Shizuku, Stella and the Hagure sisters had left the scene, Yui and the other Akatsuki members had defeated the student council members, easily, and had decided to continue their onslaught, by going after Stella and the Hagure sisters.

They had eventually found the sisters and Stella but their efforts to hurt them were impeded by Nene, who was able to single handily stop Yui, and most of the Akatsuki members, besides Ouma, with her gravity ability. Yui and the others had decided to retreat, as they had completed what they wanted to do.
