There was an endurance training session in the school pool before the training camp begins. Of course, Mineta and Denki obviously have no real intention to train. Mineta overheard the Class 1-A girls plans to use the pool to have fun, so they scheme to see the girls in bikinis after. Knowing that their homeroom teacher Aizawa would realize their real intentions and not give them permission to use the pool, they invited Izuku under the pretense of doing water-related training. Denki and Mineta were running towards the door of the pool

Denki and Mineta: "Paradise is waiting! On the other side of this door!"

They then saw Iida smiling

Iida: "There you are slow pokes!"

However, they didn't expect Izuku to invite all the boys of Class 1-A to participate in endurance training. The girls are present but they're wearing the school-mandated swimsuits. To Denki and Mineta's horror, their plan completely backfires when both are forced to train.

Denki: "I can't believe there's not a single bikini here. Foiled once again."

Mineta: "You know, school swim suits are still kinda hot."

Denki: "Have some standards, dude!"

Aizawa then said that there will be a new student to the school that will joining them and to wait.
