Poke-Yu or Yu-Mon.
My money's on the puffing Reimyu.
Reimu used Take it Easy!Reimu's speed fell.Marisa used Take it Easy!Marisa's speed fell.
I imagined something like this considering how there are people who almost seem to collect Yukkuri, but then I realized all they do is take it easy and they have no tolerance against pain so
still worth the attempt, if not for the hilarity that ensues.
Who's that Yukkuri?
There would be no yukkuri centers, because yukkuris were expendable.
Ends in refreshing.
