Two Neco-arcs drifting at high speeds while a music that i hope gets claimed plays in the background

thanks to Fox BG the song is 【東方虹龍洞ボーカルアレンジ】LUCKY CAT(原曲:大吉キトゥン)【ちょこふぁん】 I hope this gets claimed just so I know what song it is. Edit: Damn, it didn’t. Edit 2: thanks to FoxBG for finding out the song!
