When last we left off our rooster hero, Keiji, he had met his brother and was on the way to go after some devils - which can control demons. This continues that search for his father, kind of team up with his brother, and an attempt to free the good demons they had met along the way from being brainwashed by the devils.
I'm going to be real for a moment. If you like the idea of a group of literal chickens fighting monsters, then just pick this up. I don't need to tell you more. It's ridiculous.
If that sounds too absurd for you, then feel free to pass.
Also, at Hot Topic, I happened to find official Rooster Fighter merch. So, I got to wear the shirt while reading the chapter. Good stuff.
