Following the Paranormal Liberation War and Deku's return to U.A., Toru had noticed that Yuga had not smiled even once and left to check on him. After overhearing Yuga with his parents, she is shocked and horrified upon learning that Yuga was the mole within U.A. who had been leaking information to All For One. Upon Izuku’s arrival at the scene she hears Yuga admit everything. When the Aoyama family tries to flee, Yuga fires his Navel Laser defense, Toru reflects the laser beam away with her body, yelling that so many people have had their lives endangered and that Yuga had the nerve to sit in the same class and live in the same dorm as them. The light from Yuga's laser also reveals a part of Toru's face, and she is shown angrily crying because of her friend's betrayal.

Overcome with guilt, Yuga revealed how he enjoyed the fun times he had with them and how it wounded him to plot against them. Furthermore, he expressed towards his parents that he thought he was finally free when All For One was defeated by All Might and believed that he could become true friends with his classmates, showing how he truly came to care for them. Yuga becomes further emotional upon seeing that Denki and his other classmates wish to forgive him. He also reveals that the more faith they have in him, the less belief he has in himself and that he immensely fears making the same mistake all over again.
