子猫のパヤパヤ (Koneko no Paya Paya)

Background
Although Onecup-P's published many VOCALOID works in late 2007 during Miku's booming popularity, Koneko no Paya Paya was his first work to gain significant recognition and was one of Hatsune Miku's earliest hits on Niconico. The song was later featured in the game Project mirai 2.
