Hello, Happy World! releases a mini Album. This work opens with the boundlessly bright "Starring Myself", and lines up "Horebore Smile Goal!", a cheering song that pushes you forward at full power, and "Mabushii ne Sono Egao!", which is marked by a melody that makes you want to hum along. The following track "Kapon to Gokuraku Yutopia!", an up-tempo number that generously takes in a Japanese flavor, lets you feel that the possibilities of HaroHapi go on and on. And closing the album is "Smiley Carol", a song provided by OSTER project, a heartwarming Christmas song packed with the spirit of "making the world smile". The Limited Edition with goods comes with a set of five kinds of acrylic stands using the jacket illustration. Do not miss this work, in which smiles run around nonstop anytime and anywhere.
