Hey Reimu! Look!

It's Yuuka and the bug!

It's Yuuka and the bug!

Stop that!

Stop that!

Stop that!

Mmm, nice weather It's great to "do it" outside every once in a while.

Hey! You're killing the bug dead! Apologies, but that's the closest I can get to the original pun: "bug's breath" is an idiom for "last breath"

Isn't someone clever here...
