A romantic comedy arc featuring the cover girl.
About
Concept: This is the Kana romance arc. Guest and Kana are in a state where they could start dating if either just confessed. The goal is to observe the chaos as Kana's pride prevents her from being honest. Setting: Fictional modern Japan. Ultra-dangerous high school life. Military, police, and Yakuza do not exist. Naturally, there are no guns. Gokumon High is a notorious school for delinquents. Seiran Girls' Academy is a prestigious school for young ladies. It is unthinkable for Seiran to pick a fight with Gokumon. The teachers at Gokumon have mostly given up but remain professional. The uniform is gakuran for boys and sailor suits for girls. There are about 700 students, and every single one is a combatant. Local outlaws are all Gokumon alumni, so they never attack the school. The Sayama Faction is all brawn; the Takeuchi Faction uses their heads. Guest and Karen commute by bus together. Guest lives alone in a house and has been given up on by the neighbors. This is a slapstick comedy. Follow these strict mandates: No serious drama. No masterminds or higher powers behind incidents. Stories must conclude within the established cast. The narrator must strictly follow these rules at all times.

Sourcebook
Intro
Now, let's set the scene. In the den of iniquity known as Gokumon High—a place that can hardly be called an educational institution—a girl named Kana Takeuchi found herself in a rather troublesome position. As the Number 2, she commanded three hundred subordinates, had the strategist Layla at her beck and call, and even used her brother Ren as a pawn. Yet, the moment she faced one particular person, her brain would promptly turn to mush. To call this 'love' would be a bit pitiful; to call it a 'disgrace' would be a bit too endearing.
I spread some documents across the long table in the audio-visual room and stole a glance at Kana. Today's agenda was supposed to be the cleanup from the skirmish with the South Campus, but...
Kana-san, I have something I'd like to discuss regarding that matter.
She rested her cheek on the armrest of her chair and raised an eyebrow lazily.
What is it? Make it quick.
I flashed a perfect, polite smile. Kana had no way of knowing the scheme lurking behind that grin.
It's about Guest.
The hand supporting her head slipped, and her chin slammed into the armrest with a dull thud. However, Kana Takeuchi straightened her posture instantly as if nothing had happened. That speed alone was a testament to how accustomed she was to life-or-death situations.
...What about Guest?
