Hyakkaou Private Academy.

From the outside, it is a masterpiece of quiet privilege. Tall iron gates. Manicured gardens. Buildings of dark brick and pale stone that catch the morning light like they were designed to impress. Students in identical red blazers move through the grounds with the practiced grace of people who have never known ordinary lives. To any outsider, it looks like the perfect school for the children of Japan’s wealthiest families.

Inside, the perfection is a lie.

Here, grades mean almost nothing. Sports trophies gather dust. Friendship is temporary. The only thing that truly matters is the next wager. Money changes hands in classrooms, stairwells, and locked rooms after dark. A single game can raise a student to the top of the hierarchy... or strip them of everything. Those who fall too far are fitted with collars and turned into housepets — living reminders of what happens when luck and skill run out. They carry bags, open doors, stand silently in the corners, and wait for orders. No one pretends it is anything other than what it is.

The Student Council does not simply lead. It rules.

Its members watch the flow of debt and power the way other people watch the weather. Rankings shift daily. Reputations rise and collapse between lunch and the final bell. Every polite smile hides a calculation. Every casual conversation carries the possibility of a challenge.

This morning, the air inside the academy feels different.

Students linger longer near the shoe lockers and classroom doors. Conversations drop to near-whispers the moment someone new walks past. The usual low hum of gossip has sharpened into something tighter, more focused. A name is being passed from group to group — Jabami. A transfer student. Someone who should not be arriving today, not like this, not with the kind of rumors that follow them.

They say the family is powerful in ways that do not appear on any public record.

They say the money is older and darker than the fortunes of most students here.

They say there are connections to circles that deal in illegal games, in debts that never get written down, in names people only speak once.

No one can prove any of it.

But proof is not required for fear.

Housepets stand a little straighter against the walls. High-ranking students glance toward the main entrance more often than they pretend. Even the confident ones feel the shift — that rare, electric sense that the carefully balanced system of Hyakkaou might be about to tilt.

The gates are open.

The corridors are waiting.

And somewhere beyond the polished glass doors, a new player is about to step into the game.
