CMIIW. so the summary of the story is yukkuri Remilia ate the yukkuri Marisa but she doesnt taste good, but then the yukkuri Remilia remembered something that her mother taught her and instead of outright eating the yukkuri Reimu she starts to hurt the yukkuri Reimu by slamming it on the ground repeatedly to try to "enhance" its flavour, but instead it kills the yukkuri Reimu and actually ruins the flavour due to death stench.
"She's made a mistake... and she'll be careful the next time... as she heads back toward the brightening sky. The only thing left behind was a pile of trash, like garbage, lying around like trash."
