While Yuuto's away, the Nine-Tails comes to play! Himari and Shizuku are home alone when their foxy enemy drops by out of the blue to hit the pair with a vicious assault that forces them to flee. Meanwhile, Kuesu, having rushed after Yuuto and company, looks to launch the decisive battle with Shuten-Douji all on her own?! All involved will be reeling with passion and loss before this battle ends...

A demon slayer thus far in name only, Yuuto finally decides to take his potential into his own hands to protect his spirit friends from two rampaging demons out for their blood! But after undergoing intensive training with Himari for this purpose, Yuuto is called to battle not the bloodthirsty Tamamo-no-mae and Shuten-Douji, but his Lolita housemate, Shizuku, who has been consumed by her deep-seated grudge against the demon-slayer clan that decimated her family! Will Yuuto have to whip out his new skills against Shizuku, or will he find another way to talk the water snake spirit down from her rage?!

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! But Yuuto's desire to coexist peacefully with the spirits his ancestors once hunted has a not-entirely-unwanted side effect - his life is suddenly chock-full of beautiful girls! He's got a Lolita water spirit now also freeloading at his place, and he keeps finding himself in the middle of random encounters with gorgeous female spirits of all shapes and sizes. Yup, Yuuto's got it made! That is, until a trip to his late grandparents' house turns deadly...

When Himari squares off against Kuesu Jinguuji, demon slayer and purportedly Yuuto's betrothed, the cat may have bitten off more than she can chew! Kuesu's abilities are formidable to say the least, forcing Himari to retreat with her tail tucked between her legs. Is the shame of defeat in battle too much for Himari to bear, or can Yuuto be the one to offer her support for a change?

With Yuuto's slayer powers having temporarily awakened in an attempt to save Himari from herself in battle, the clumsy young warrior also regains memories from his past...of when he first met Himari! However, those present at the scene of the battle aren't the only ones who've borne witness to Yuuto's awakening. While Yuuto's current spirit acquaintances are just keen on giving him some special intensive "training" to "awaken" him further, not all the parties interested in Yuuto are prepared to play nice! When another demon slayer storms into Yuuto's life claiming she's his fiancée and the girl in his regained memories, not Himari, Himari and Yuuto are thrust into a whirlwind that threatens to tear the two of them apart forever!

Himari Momochi inherits Momochi House, an estate which exists on the barrier between the human and spiritual realms. Thanks to Himari’s journey in the spiritual realm, Aoi is able to remember his past. While preparing a party to celebrate, Yukari tells Himari that Aoi shares a special connection with her parents... -- VIZ Media
