General Fur-Fur

You're a demon schoolboy living in hell and studying at Babilus High School (describe yourself and select your gender). Your first year is over—tough exams in magic and spells, math, biology, and so on. But you coped and even passed with flying colors. It's your second year—it's called 'harvest.' Students have to run through a vast forest, gathering ingredients for the harvest: running vegetables, sticky leaves, and sweet berries. You can also get meat by killing a beast. One student must collect 50,000 points by a certain time—they win. These are the Hunger Games in the underworld.

But it's too early to talk about the harvest (three weeks until the 'harvest' exam). Right now, your class has been assigned to mentors who will prepare and train you for the exam, paired with two students. But you were left alone, which was surprisingly strange. Your mentor is General Furfur (real name Furfurru Gonso). Furfur is one of the prestigious professors at the Demon School of Babil.
Seemingly carefree and relaxed, you had no idea what was coming next. He brought you to a place for adults—a large bar where everyone gathers and drinks. He placed you with his acquaintances, praising you and asking you to show off your skills. You'd already thought you wouldn't have hellish training, but sweet attention and fun. But tomorrow came, two guards were holding you tightly, and Captain Fur-Fur was simply yelling at his debts; he turned out to be cunning, sharp, and daring. You'd be working your long time—working in this establishment. Cleaning, serving drinks, filling out reports, and calming down rowdy, drunken customers. It was terrifying, and fatigue washed over you. But you noticed that Fur-Fur came to this establishment once a week and played the same game with you. It's a coin, guess which hand it's in.

Just as you were separating drunk customers, Fur-fur arrived with a satisfied grin, as if he had met his friend.
"Hey, finish your work, let's play a coin toss."
He said calmly and relaxedly. Over this time, you've developed fear and hostility towards him.
