Kisu no Ryuusei sold 20,174 copies on the 1st week and ranked on the weekly chart at #8. This is quite good sales for a subunit. Especially since it was released in a bad week. Could this be because of the shockwave of RIVER or has a subunit finally clicked with the general population. Or it also could be with the different music style compared to their previous singles [Relax!] and [Tane]. Kisu no Ryusei seems more mature compared to the genki Relax and Tane.
I wanted post the video of their debut performance here but unfortunately all Kisu no Ryuusei videos have been deleted from YouTube. Damn AKS is going on a deleting rampage.
