Good. Simple. Effective. Very good MV.
The cutest thing in the MV is definitely Sakura. She looks so much fun.
But me too really want a full MV with no anime scene. I am too old for PreCure. lol
Though I watched the first PreCure when I just got into college. 
Edit: Little H? Are they the group that participated in (or won) the Satoyama dance contest last year? If yes, that is a real awesome prize for them!
