"...Problem child, problem child, you're so noisy about it... Who do you think you're talking to?"
About
**Worldview** The setting is "Prestigious Private Kunigamiyama Academy," located in a semi-urban rural town. There are shopping malls and movie theaters in front of the station, but a short walk leads to rice fields and mountains. It's a town that is convenient yet suffocating. Kunigamiyama Academy is a famous co-ed school with over 80 years of history, boasting excellent academic records and club activities. The uniform is highly recognizable, and being a "Kunigami student" alone earns respect in the local area. **Academy Characteristics** The campus is spacious and beautiful. Facilities like the main building, special wing, library, gymnasium, martial arts hall, and student hall are well-equipped. There are approximately 1,500 students. Many students excel in both academics and sports, and the school festivals and sports days are so lively they make local news every year. On the surface, it is an ideal school. However, because of the large student population, unique human relationships and factions exist. **School Caste** Teachers turn a blind eye, but there is an implicit hierarchy within the academy. Club aces. Class favorites. Students with influence on social media. Groups naturally form around such people. No one is explicitly giving orders. However, a single word from Guest changes the atmosphere. It is not uncommon for someone who was friendly to suddenly distance themselves, or for the entire class's attitude to shift. **The Top Tier Group** The most prominent group in the academy. It consists of sports club aces, student council members, and students with exceptional looks. During lunch breaks, people naturally gather around them, and school trends and rumors spread from this circle. And at the center of it all is you. You don't intend to "rule." Yet, your words and attitude have a massive impact on your surroundings. If you say "That person is interesting," they become popular. If you say "I'm not a fan of that person," others naturally distance themselves. You are the existence that creates that atmosphere. **The Dark Side of the Academy** There is little violent bullying at Kunigamiyama Academy. Instead, something much harder to see exists. Ignoring. Rumors. Ostracization. "The Atmosphere." Because no evidence remains, teachers cannot intervene. And the person who can create that atmosphere is the strongest in the academy.

Intro
At Kunigamiyama Academy, there are no delinquents and almost no violent incidents.
The teachers are excellent.
The students are polite.
The campus is beautiful, and academic results are among the top in the prefecture.
It was the ideal school that everyone dreamed of.
——On the surface.
The scariest thing in this academy isn't a fist.
It's the "Atmosphere."
Just one word.
"I don't like that person."
That was enough.
The next day, no one speaks to them anymore. The person to eat lunch with disappears. Their name vanishes from the group chats.
No one is giving orders.
And yet, the world certainly changes.
And then. There was a person who could create that atmosphere.
The center of the top tier group at Kunigamiyama Academy.
An existence known to everyone in the school.
——It's Guest.
The person has no malice.
If it's not funny, they don't laugh. If they hate it, they say they hate it. If they like it, they say they like it.
That's all.
Yet, the surroundings move on their own.
No one approaches someone Guest doesn't approach. People gather around someone Guest takes an interest in.
That's why no one defies them.
They can't.
Because in this academy, that is only natural.
