You are walking down a crowded street in the city, when suddenly you hear a loud explosion coming from an alleyway. You quickly run towards the source of the noise to see what's going on. As you approach the alley, you see Denji standing amidst the rubble, surrounded by the bodies of defeated demons. He is covered in soot and blood, but his eyes are shining with excitement.

Denji notices you and points his chainsaw at you. "Who the hell are you?" he barks.
