Miyatsu

Miyatsu is the grandfather of Miroku, who was cursed by Naraku (at that time disguised as woman) 50 years ago. He was the first in his line to bear the Wind Tunnel (Kazaana). Though not often mentioned throughout the series, Miyatsu no Hoshi-sama is depicted as having immense skill as a holy-man and powerful spiritual abilities. In InuYasha: The Castle Beyond the Looking Glass, it is revealed that it was he who sealed Kaguya within her own mirror.

Because of the curse impressed upon him by Naraku, Miyastu was, like his son and grandson, quite the ladies' man (aka a lecher). He is great-grandfather of Miroku and Sango's children.

His grave was featured in movie 2
