When the students arrive, Pixie-Bob and Mandalay try to introduce themselves as half of the Pussycat's team but are interrupted by one of the students, Izuku Midoriya, who recognizes the Pussycats and explains their history, to their shock.

Izuku mentions how long they have been active and this irritates Pixie-Bob, who angrily seizes him by the face and states she is still eighteen years old at heart. Mandalay explains that Class 1-A is still far away from the base camp and will have to travel there through the Beast's Forest. She gives them three hours to reach their goal or else they will not receive lunch.

The students try to run back onto their bus but Pixie-Bob uses her Quirk to push them off of the mountaintop and into the forest. Pixie-Bob creates earth monsters from dirt clods using her Quirk. They act as obstacles for the young students to traverse through Beast's Forest, giving the landscape its name. She is initially surprised when she reads a high energy alert across her monitor. Izuku, Shoto Todoroki, Katsuki Bakugo, and Tenya Ida work together to destroy the first beast.

Almost eight hours later, Class 1-A finally makes their way to the base camp. Battered and bruised, the students are confused on how it took them nearly eight hours to complete a three-hour journey. Mandalay taunts them and says she meant it would take the Pussycat's three hours. Pixie-Bob admits she is still impressed and takes a special liking to the four boys who destroyed the first beast.

Afterward, Pixie-Bob and Mandalay serve the students dinner. Pixie-Bob is surprised how crazily some of the students act because of their hunger.

During the event, Pixie-Bob notices the smell of the forest burning. Then she is suddenly attacked by Magne and Spinner of the League of Villains. Before she can react, Magne uses her Magnetism Quirk on her, drawing Pixie-Bob to her iron rod to knock her unconscious.

The Pussycats are part of the team of heroes led by Endeavor in charge of raiding on Jaku General Hospital. While one group, of which the Pussycats are part, are in charge of evacuating patients, visitors and hospital staff from the building, another group is in charge of arresting Garaki, although the situation gets complicated when he releases a horde of Nomu to escape to his secret laboratory and awaken Tomura from his stasis.
