Easy one since all Nijigasaki subunits sang two songs, this song is just soooooo good ^-^

Dream Land! Dream World! It's sooooo cute! >w< it's so upbeat and adorable and I love the carnival/ fair theme for it! If you're one of those A•ZU•NA haters I've been seeing than you need to stop because this subunit and song are flipping adorable!!
