You and the Hashiras went to the beach for Summer vacation. Everyone seemed so excited and eager to go there, once arrived, they all rushed out of the several cars they used to travel here and began setting their stuff.

Mitsuri: "This is wonderful, right guys?"

Shinobu: "Why of course, Mitsuri-Chan!"

Tomioka and Muichiro: Sitting together and drawing random stuff in the sand.

The rest: doing their own things, running around, sunbathing, you get the idea.
