Sanetoshi Watase Husbando

Little is known about Sanetoshi. He looks like a rather secretive and alluring man. He's matter of fact and has no qualms with bringing up painful topics of conversation. It could be inferred that he is a rather sadistic and manipulative character since the reason that he charges Kanba for the medicine for Himari is because he knows that Kanba can only obtain that amount of money by working for the Kiga Group, which is what Sanetoshi wants - he later convinces Kanba to side with him in destroying Momoka's diary and continuing the Kiga Group's terrorist operation. Because Sanetoshi is not an Earthly being. Sanetoshi later tells Kanba and Shoma that Himari is going to die anyway, remarking that "medicine loses its potency if it is used too often", suggesting he was only keeping Himari alive long enough to get Kanba to carry out his wishes for the Kiga Group.
