Burial of Shortcake

"Sweat, dirt, blood. It all goes in my mouth and makes me want to throw up."

One night, the main character, Kisetsu, sneaks into a mountain forest in the middle of the night in order to bury the corpse for a certain reason.

A snow shovel.

A shopping cart from a supermarket.

And then he wrapped something in a blue sheet and hid it - [that].

Surrounded by “them”, he started digging a hole, was covered with all the sweat and swallowing blood and dirt.

And then...

“What is that…?”

He just realized that there is no end beyond the hole and beyond the tragedy.

This is about “the world” beyond the tragedy.
