While the episode starts with a brief recap of the past, it swiftly moves to a current timeline with the introduction to the characters. Shiki Ichinose, the main protagonist, is a gun fanatic who has recently been expelled from high school. Soon, his father, Tsuyoshi Ichinose, storms into his room and asks him to explain the matter.

Tsuyoshi runs a liquor store and is losing his clientele, as Shiki mentioned. However, he is not Shiki's blood-related father, as revealed in the episode. After receiving a phone call for a beer delivery, Tsuyoshi leaves the house, and moments later, Shiki hears a loud noise outside.

A black-matter, looking like a whip, comes inside and drags Shiki outside through his window, where he meets a tall, stoic man asking his identity. Before Shiki can say anything, Tsuyoshi drives his car and runs over the man, asking Shiki to get inside quickly. Without asking any further questions, he gets in the car and they drive off, suggesting they might have to leave the country.

As they are driving, upon Shiki's inquiry, Tsoyoshi reveals that Shiki is a descendant of the Oni and has demon blood running through his veins. However, the man catches up to their car as they drive to a nearby abandoned warehouse. The car explodes after Shiki and Tsuyoshi get out of it.

After reaching the warehouse, Shiki is isolated and is caught by the man, who reveals his identity. The man is Samidare Momoya, a member of the Momotaro Agency. As Tsuyoshi rushes inside the warehouse, Samidare reveals that Tsuyoshi is a former Momotaro and used to be his mentor, after he calls him "Sensei".

The Momotaro has only one objective: to kill all the Oni and their descendants, and this rivalry has been going on for ages. However, Tsuyoshi does not falter and stands up against Samidare from killing Shiki. However, Tsuyoshi is easily overwhelmed and gravely injured by Samidare during their fight.

As Samidare is going to land the final stab to kill Tsuyoshi, Shiki gets overwhelmed with emotions and starts transforming. Within a few moments, Shiki transforms into his Oni form, wielding guns and weapons conjured from his blood. After an intense fight with Samidare, Shiki is able to get the upper hand. However, he transforms back into a human, allowing Samidare to kill him.

As Samidare charges to stab him, Tsuyoshi intervenes and sacrifices himself. He takes the stab to save Shiki and kills Samidare. While Shiki tries to rush Tsuyoshi to the hospital, the latter exclaims it is unnecessary and gradually passes away after a moment of bonding between them. Meanwhile, a guy named Naito appears and knocks Shiki unconscious.
