Maruo Kaido vs. Nyudo Inokuma is a battle between the Urara Family member Maruo Kaido and Nyudo Inokuma.
Prelude[]

Maruo steps in to help the harassed Ayashimon.
While at a bar discussing plans to find a base of operations in Kabukicho for their gang, Maruo and Urara take note of an Ayashimon named Nyudo Inokuma harassing a lackey Ayashimon after the boy attempted to deceive him and his gang. After being asked by Maruo if they should help, Urara states her objection and that they should think about stealing the boy's gang territory once the dispute has ended. However, after Nyudo goes too far by kicking the Ayashimon to the floor, Maruo gets up from his seat and tells the harassed Ayashimon that he will defend him in exchange for his gang's office.[1]
Battle[]

Maruo defeats Nyudo.
Becoming annoyed that someone has butted in on his business, Nyudo releases his true form and attacks Maruo with a blazing punch. However, Maruo blocks it while noticing how strong the attack was and takes the time to tell Urara his belief, which is "the strong feeding on the stronger" rather than her earlier statement on how its "the strong feeding on the weak" to survive Kabukicho. Maruo then turns his attention back to Nyudo after the Ayashimon releases a breath of fire his way, which excite Maruo. To counter, Maruo uses a steel door as a shield but soon realizes that it was not the best strategy after feeling the heat conducting from the metal door. Maruo then hears from Urara that he should use the sprinklers to put out Nyudo's flames by redirecting the breath of fire upwards. Maruo finds this to be a great idea but uses his own strategy instead by jumping up and destroying the water pipes in the ceiling to cause a downpour. With Nyudo being limited to just his physical strength, Maruo charges towards him and defeats the Ayashimon with a special attack, which Urara tried warning Maruo not to do until they had setup an official ritual duel.[2]
Aftermath[]
After the squabble was over, Urara yells at Maruo for causing a scene and bribes the bar manager to keep quiet by offering Nyudo's money reverted body. Seeing Maruo's amazing strength, the harassed Ayashimon named Ten asks him to be his underling and willingly leads him and Urara to his gang's office.
Later, the Onmyo Bureau receives an alert about the fight involving an undocumented entrant.
