Plot
Kōsuke, together with the other kids, welcomes Akutagawa at their place. The orphans gathered to Akutagawa in which he cannot do anything about it. The children continue to play with Akutagawa's Rashomon in which he transformed as a slide for the children to play with.

Kōsuke serves a meal to Akutagawa at the restaurant as a thank you gift for playing with them. Kosuke then brags that he made the recipe himself to which Akutagawa asks if he wants to become a chef in the future. Kosuke responds that Oda is a like a big brother to him, and he wanted to be strong like him, enough to join the Armed Detective Agency. Kosuke then tells Akutagawa that he served him a meal in exchange for a combat training.

The two then starts to train. While training Kosuke who is badly injured, Akutagawa tells him that he might appear as winning but Oda will tear him from limb to limb if he had to face the burden of arranging a funeral for his brother. Akutagawa then gives Kosuke a chance to attack him. Kosuke, without hesitation, charges to Akutagawa in fast pace however Kosuke failed to attack him. Akutagawa then tells Kosuke that he hate weak people and tells Kosuke not to compare himself to Oda since he won't become like him even in the end of his life. Kosuke rejects Akutagawa's statement. Suddenly, Akutagawa points a gun to himself to which he states that he also hates guns. He starts to shoot but blocks the bullets with his Rashomon. He tells the reason he hate guns is that his group of friends in the slums were shot by guns. He then throws the gun and tells Kosuke that weak people don't have the privilege to determine one's actions and next time he will kill him.
