ビバハピ (Viva Happy)

Background
"Viva Happy" is Mitchie M's seventh original work, sung by Hatsune Miku. Mitchie M commented that he tried to tune Miku to sound like a "Japanese animation voice actress" (specifically, Saki Fujita, Miku's voice actress). Like all of Mitchie M's VOCALOID works, it is noted for the realistic quality of Miku's voice.

"Viva Happy" is featured on Mitchie M's album グレイテスト・アイドル (Greatest Idol) and the compilation album VOCA NICO☆PARTY.

This song has entered the Hall of Legend. It topped the niconico Weekly VOCALOID Ranking during weeks 304 and 305.
