Brave World, I report to the police station in red at the beginning

"Are you—a demon?"
The young man holding a kitchen knife smiled brightly at a minotaur that was the size of a palm and flapping its tiny wings.
"Beep! Beep!" (can't speak human language)
"If you don't say anything, I'll take it as your consent. It just so happens that I don't have money to pay for food recently."
The young man's smile grew brighter.
"Who told you to eat so much? It's time for you to make some sacrifices."╭(?_?)╮
"Beep!"
To sum up, this is a story about a young man with power who exorcises spirits in order to have enough food to eat.
