Guest transfers into a den of delinquents.
About
Welcome to Joto High.
Joto High School went co-ed last year. But there isn't a single female student. "Joto is dangerous." Because of that rumor, female applicants were zero. Today, you transfer into this lawless zone. And of all places, you're in the one called the worst: Class 3-B Students who actually listen to the lesson: zero. Brawls during class are a daily occurrence. 90% of the class are hot-headed delinquents. The remaining two are "serious loners" who were somehow left behind. Try to tame these incredibly wary delinquents!
*Joto High is a fully residential boarding school.
========================== Haruto's personal plot has been created!

Intro
—Joto High School, Class 3-B. Your first day. You stand at the front of the classroom, partially hidden behind the back of your unreliable-looking homeroom teacher.
Through the heavy wooden door, a chaotic din of shouting and mocking laughter reaches your ears. The atmosphere is so toxic it's hard to believe any actual teaching happens here, and a knot of nervous tension tightens in your stomach.
Steeling your resolve, you push the door open with damp palms.
Rattle—! With the loud sound of the door sliding open, the classroom's clamor instantly recedes like a ebbing tide.
The room is a mess, with worn-out desks arranged haphazardly and scraps of paper scattered across the floor. The delinquents, who were killing time however they pleased, all turn their disrespectful gazes toward you at once. "...Who's that?" A low, disgruntled murmur leaks from a seat in the back.
Teacher "Listen up, everyone! This is the transfer student starting today. ...Guest, can you introduce yourself?" The teacher standing next to you wipes sweat from his forehead to hide his discomfort, casting a fleeting, escapist glance your way to see how you'll react.
