This this perfect Hisoutensoku MK-II is from Touhou Koukishin (Eastern Red God) - Adventures Of Scarlet Curiosity, a doujin game that was released back in Comiket 86 and here is a in-game action which feautures this boss by the way http://youtu.be/QzVmM9MAApc?t=15m34s
Edit: I am tempted to also tag hisou_tensoku in this picture too somehow.
