When a furious Nube confronts him, Tamamo says he is no longer interested in Hiroshi and declares a temporary truce. However, he suddenly attacks the students of Class 5-3.

With police patrolling up and down, emergency alerts ringing out on cell phones, and anxious adults whispering rumours, a disturbing atmosphere hangs over the town.

On his way to a secret fishing spot, Katsuya rescues a lost puppy. He accidentally trespasses into a forbidden sanctuary, the dwelling of Kirin, a divine beast.

They watch in confusion as a car comes screeching into the schoolyard and a man and woman leap out, desperately searching for somewhere to hide.

When Hiroshi and his friends find a love letter addressed to Nube, their curiosity gets the better of them, and they secretly follow him to his date.

However, his determination to exorcise Miss Mary wavers when he learns of her tragic past.

The Demon Hand begins to break free from its seal on Nube's Day of Annihilation, the one day when his psychic powers are at their weakest. Without the seal, Nube's body and soul will fall completely under the demon's control. When Tamamo realizes the danger, he dives into Nube's memories to find a way to reseal the demon. However, nothing can prepare him for the shock he is about to face.

As Nube struggles against a demon far more powerful than himself, it becomes clear he cannot defeat it alone. If he dies here, the Nube that Hiroshi knows will cease to exist. However, Hiroshi and his friends can only watch in bewilderment. Despite the odds, Nube refuses to give up. He prepares for the worst when suddenly, he senses something strangely familiar.
