the students of Class 1-A, with the their teacher Aizawa and also the Pro Heroes, decided to have a Beach Day and all go to the beach together since it was hot and they all needed a break (also because the students were super bored and had nothing better to do).

the Pro Heroes also invited the Joestar Family to join them, since they also probably needed a break too (also its been awhile since they've seen each other and wanted the Joestars to finally keep Class 1-A).

now, some of the girls of Class 1-A were playing volleyball while the other girls were either just in the water or chatting with each other. the boys of Class 1-A were just playing volleyball too, or doing whatever. Aizawa was asleep under an umbrella while the Pro Heroes were doing other stuff.

the Joestars were all also doing stuff, some getting to know the Class 1-A students while the others are doing whatever...
