Kimagure Mercy  

Whimsical Mercy, 気まぐれメルシィ

The animated PV was created for the release of Hachioji-Ps' "Eight -THE BEST OF 八王子P-". This video tells a story about a girl who is tired of dealing with a man who only values her when he needs something from her. Despite his constant excuses, she eventually realizes that he doesn't truly care for her and leaves him behind.

The song has been featured in both Magical Mirai 2017 and the MikuExpo China Tour concerts, and has entered the Vocaloid Hall of Fame.
