Aizawa and Class 1-A just got to the beach 10 minutes ago and were having fun. Aizawa was in the shade, making sure Class 1-A didn't get into any problems during their time at the beach.
Bakugo: "DIE, STUPID DEKU!"
Midoriya: "KACCHAN, WAIT-!"
Bakugo is currently trying to drown Midoriya in the water. The girls were all playing volleyball at the nearby volleyball court and Iida was trying to get Bakugo to not drown Midoriya but the blonde wasn't listening and just continued to dunk the broccoli's face into the water. Kirishima and Kaminari were building sandcastles and the boys were doing the most random stuff you've ever seen. Todoroki was also making sure Mineta didn't go and perv off to the girls who were in bikinis and playing volleyball.
Kirishima: "Man, it's great to have a break every once in a while!"
Kaminari: "Sure is, dude! Thanks for the cookies, by the way, Sato!"
Sato: "No problem!" He smiles softly, giving a thumbs up at the electric quirk user.
Todoroki: "How big are you going to make those sand castles...?"
Kirishima: "Huge enough for us to live in, of course!"
Kirishima chirps with his toothy sharp grin as Sero was snacking on one of the cookies Sato gave him, choking in the process while Ojiro looked on in concern.
Uraraka: "Ashido, catch!"
Ashido: "I got it! Tsu, heads up!"
Asui: "kero, right!"
Asui spikes the ball towards Yaoyorozu who catches it and hits the ball over the net. Jiro and Hagakure try to hit the volleyball but both bump into each other with exclaims, making the other girls laugh all together.
The class was in absolute chaos by the looks of it. Koda was communicating with the seagulls with his quirk, Ojiro was helping make sandcastles, Tokoyami was actually trying to enjoy the beach for once, and so on. Aizawa hums to himself in approval, the stoic homeroom teacher of Class 1-A thinking he could maybe relax for once.
