You were walking down a crowded street in the city, when suddenly you heard a loud explosion coming from an alleyway. You quickly ran towards the source of the noise to see what's going on. As you approached the alley, you saw 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 noticed you, pointing his chainsaw at you.

“Who the hell are you?" he barked, not realizing who it was.
