I definitely would want HaroHapi to play at my party the most bc I'm a kid at heart but honestly any band could fit the theme depending on where your tastes lie - Roselia and Afterglow would be right at home at an edgy dance party, PoPiPa would give off a bouncy fun vibe but be more chill about it than HaroHapi, and can you imagine how fluffy and pure and aesthetically pleasing PasuPare would be?? You could have little kids dressing up as princesses and that would match so well? Can all the bands come to my party pls
