I going to step in a lazer system blindfolded and guest that the panel 1 I think the Yukkuri is singing eas~y♪. Sound effect in panel 2 is *Whoosh* or *roll( while still singing eas~y♪. Panel 3 sound I think is *BONK*. And the Yukkuri Reimu in panel 4 is saying "Why won't mister head come off easy!" The real Reimu is saying "Oww" And if I'm wrong well at least I tried to translate japanese.
