Denji decides that his new dream is "to fondle some boobs."

His partner, Power the Blood Fiend, offers to let him feel her boobs only if he rescues her old pet cat Meowy from a devil.

With his dream in sight, Denji is all fired up and ready to go, until...

After a fierce battle, Denji defeats the “Bat Devil” and rescues Power even after she had trapped him.

He says it is all for the sake of “touching Power’s boobs”.

Power mocks his ridiculous motivation saying “that’s a pretty dumb reason”, but still agrees to let him fondle her boobs.

As Denji gets thrilled with the idea, he faces a sudden attack from out of nowhere...

Aki Hayakawa, Denji, and Power start living together.

Denji finally fulfills his dream of touching Power’s boobs, but is shocked when things do not turn out the way he expected. As Denji realizes that chasing his dream was more fun than achieving it, Makima approaches him and says, "If you can kill the Gun Devil, I’ll grant you one wish.”

Denji and Tokyo Special Division 4 members enter a hotel to collect a piece of the Gun Devil. However, they end up being trapped on the 8th floor due to the devil’s extraordinary power.

With the members being cornered on the endless 8th floor with seemingly no way to escape, the devil makes them an offer: “If you let me eat Denji, I will let all of the other devil hunters leave in one piece.”
