Hisui

is Miroku and Sango's son.

History
Miroku and Inuyasha were off exterminating a Yōkai while Sango was giving birth to her third child. Rin and Lady Kaede were present during the birth. The birth had been successful by the time Miroku returned to his family.

Years later, Hisui became a yōkai taijiya under the leadership of his uncle Kohaku, and inherited Hiraikotsu from his mother.

Weapons

 * Hiraikotsu: Hiraikotsu is a gigantic boomerang that Hisui inherited from Sango. This boomerang is made up of various kinds of yōkai bones. Hiraikotsu requires a lot of strength to throw in order to destroy the target. It is a fierce weapon, possessing a great amount of power when thrown by a sufficiently strong user, to the point of severing most natural defenses of yōkai.
 * Yōki and Miasma Dispersion: Hiraikotsu can emit demonic aura, allowing it to inflict greater damage to enemies. It can also absorb miasma/poison and disperse it safely.

Kohaku
Kohaku is Hisui's uncle and later his mentor, after becoming a yōkai taijiya.

Kirara
He appears to be Kirara's new partner.

Trivia

 * Just like his mother and his uncle, Hisui is named after precious material used to make jewelry.
 * The rosary on his left wrist is a visual callback to how Miroku's nenju sealed off the Kazaana in his right hand, and possibly how Hisui himself was spared from having the curse at all.
