Another morning fighting with Tora followed by going to school with Asako. However, an organization named HAMMR breaks the usual cycle. The three mad scientists of HAMMR kidnap Ushio and Asako and Tora go after them in an attempt to save him.

Ushio, anxious over the approaching decisive battle with Hakumen, runs into Asako on the way home from school and ends up arguing with her as usual.

After being tricked by Hakumen no Mono, the JASDF prepare to send subs to destroy the stone pillar where Ushio's mother is, as she keeps Hakumen sealed. Ushio heads to Okinawa to stop them, but runs into Nagare, who seems to have switched sides. Ushio leaves Nagare to Tora, and hurries to stop the subs. Nagare and Tora go all out in battle, and Asako finds out a secret about Ushio...

Mayuko pulls her soul out of her body to support Tora. The allied forces of human and yôkai restore the bonds among themselves to beat Hakumen.

Hakumen crushes its eyes itself to overcome the fear of the Beast Spear. Tora wants to save all the people even if it has to sacrifice itself, and tells the strategy to Ushio.
