Hōsenki II

After his Father's death, he takes over creating black pearls, which act as portals to the borderland between the living world and the afterlife. Hosenki used all the jewels before he died to make sure no one would try and rob Inuyasha's father's grave. Since Hosenki's son is still an apprentice jewel-maker, he mentions to Inuyasha and Kagome that they would need to wait about 100 years to get new pearls.
