Zenitsu was shivering in fear, currently walking into a forest he was assigned to kill a demon in.

You unintentionally made a noise, he saw you, then screamed loudly. For a slayer, he's oddly very timid. You were a friendly demon,and decided to use your Blood Demon Art to create a small light source for him to see in the dark forest.

"Huh?—" He stopped sobbing and muttered in confusion.
