The East/West youkai decide Asako can go on her merry way, but Mayuko is to be sacrificed. Obv., Asako ain’t taking that sitting down, and tries with everything she has to fight back, but the monsters are too strong.
Asako’s only kept from being killed by the barrier when Mayuko starts flexing her oyakume descendant muscles, saving her with a protective magic. I’ll admit, it’s a little strange seeing Mayuko use magic, but all this hullabaloo seems to have awakened her true power.
Mayuko is willing to be thrown into the forge, but Asako stops the youkai, and offers herself as a sacrifice so Mayuko can perform her duties as the oyakume. Mayuko doesn’t like this one bit, but she can’t stop Asako from sacrificing herself. Only Ushio and Tora, arriving in the nick of time, can do that.
For a second there, I really thought this was the end for Asako, which would make things very tragic indeed for Ushio, who’d have to carry on fighting Hakumen having lost one of the people most important to him in the world. Indeed, Asako only remembers Ushio when she’s about to leap into the flames—and she does leap in—but Ushio jumps in before her and catches her.
Both of them are badly scorched, and the youkai start attacking them mercilessly for interrupting their plan, but Tora steps in to take the punishment, and Mayuko uses her magic to protect them and eject them from the building.
Of course, things aren’t any safer out there: a Tora lookalike named Guren has arrived to fight the youkai and destroy the Beast Spear on behalf of Hakumen. Guren’s crew and the youkai engage in an aerial battle while Ushio, Tora, and the girls fly away with Jeimei.
Saya enlists Kappa to help heal Asako’s burns, but Ushio doesn’t have time for medical attention, and rushes back into the fray, even against those who no longer know who he is and don’t wish him well. Tora, unable to let his meal get killed by someone else, soon follows him, and the two show the youkai how well they fight together, and that the present Beast Spear is still a powerful weapon.
Before Ushio returns, Mayuko leaves with Jeimei to fulfill her destiny, leaving Asako with Saya and the Kappa. When Ushio and Tora get back, Mayuko is gone, but Ushio doesn’t persue her. He knows he was lucky to come away from the day with one of his friends alive and free. He’s going to trust in Mayuko’s strength, get back to the fight with Hakumen, and eventually come to get her back.
Things are still in a pretty dark place in Ushio to Toraland: Asako’s in bad shape, while most everyone still forgets who Ushio is, and may well still be convinced a new Beast Spear needs to be forged. I’m guessing he has to address the mass amnesia (which is likely curable) and get his allies back before he can fight Hakumen in earnest. Lots of trials still ahead for our hard-headed protagonist.
