As expected, Satoru is saved from falling to his death by Ushio’s spear, but despite Jun temporarily getting through to him, his body and mind remain possessed by the Hiyou. Watching Jun shed more tears for her all-but-doomed brother, Ushio can’t sit back or get on with his own business. Not while a girl is crying. He’s going in!
To aid Ushio on his foolhardy, extremely dangerous and possibly soul-rending mission into Satoru’s body, the Elder of Ungaikyou lends the services of a youkai used to such trips, the fuzzy green Izuna. He may be tiny, but he makes an immediate impact, as new characters on UtT tend to do.
This then becomes a Very Special Magic School Bus–style journey into the body, with Ushio, Tora, and Izuna being shrunk down to the size of microbes, travelling between bones, muscles, and organs to battle Satoru’s Hiyou infestation as Jun, Nagare and the others hold him down.
The concept’s more than a little silly, but I appreciate the audacity nonetheless, as well as the dual perspectives on the battle. Also, the more Ushio battles, the more of his soul the Beast Spear takes, and that spear is probably playing for keeps.
When the trio nears Satoru’s brain, they meet the Hiyou boss, Chibakama, who then gives Ushio a glimpse of what his boss Hakumen no Mono looks like in order to frazzle the kid further.
Ushio initially says he has nothing against Hakumen personally, but that’s only because he knows so little about him. In reality, Hakumen is all but pure evil; the manifestation of the world’s hatred. He’s not just Ushio’s enemy, but the enemy of all living things and monsters alike.
Izuna sacrifices his body to stop Chibakama from killing Ushio, in doing so taking a selfless page from the Beast Spear wielder himself. Meanwhile, Tora sets up a plan to rid Satoru of Chibakama once and for all; a plan that requires Jun to disrobe and summon her anti-youkai power in the nearby river. Alright then!
Using Satoru’s eyes as a conduit between the world within and without him, Satoru shoots all her power at Chibakama, being held in front of the eye by Izuna, who fully intends to die with him.
Ushio doesn’t let that happen. Instead, he tells the spear it can take the rest of his soul if it means he can stop others from dying for his sake. The combined power of Jun and Ushio petrify and destroy Chibakama, and Satoru wakes up himself.
When he hears the person he admits he was jealous of (thus allowing the Hiyou into his body), he cries tears both of guilt and gratitude for his still-absent saviour, and wouldn’t you know it, inside one of those tears is Ushio, Tora, and Izuna! Again, very goofy, but the show sells the shit out of everything it lays out.
Jun then finally gets to thank her bro, only to learn he knew she was grateful anyway, and had been thanking him by accepting him, loving him, and staying by his side, even when he falls. As for Ushio, he’s glad he stopped another girl from crying tears of despair…but he should probably revise his goals to allow tears of relief, gratitude, and happiness.
Oh, and then there’s the matter of the Beast Spear transforming him into a grotesque, inhuman beast with demonic crystal eyes. No good deed goes unpunished!
