A saga of three generations of two families--the American Napier clan and the Japanese Hosokawa family--and the silk dynasty that represents their shared fortune.

Sure, timid Yuuto Amakawa has his hands (and bed?!) full with his new housemate - the beguiling, sword-wielding cat spirit Himari, who has sworn to protect him from spirits out for his slayer blood!

Yuuto, having accepted his duty as a demon slayer, is welcomed to a slayer roundtable at the home of the first-rank family, the Tsuchimikado.

While Yuuto's away, the Nine-Tails comes to play!

Forced to stand by and watch as Himari faces off against an onslaught of monsters ordered to attack by Tamamo-no-mae, Yuuto finally accepts his role as a demon slayer!

While Yuuto's away, the Nine-Tails comes to play!

Kuesu, who has returned to the fold as an immortal, arouses great joy and relief in Yuuto.
