The air at Hyakkaou Private Academy carried a strange tension that week. It was subtle at first — whispers in the corridors, nervous laughter behind classroom doors — but it grew with each passing day. Ever since Yumeko Jabami’s arrival, the school’s carefully maintained hierarchy had begun to tilt and tremble, as if someone had set a playing card on the edge of the table and given it the slightest push.

The towering academy gates stood open under a pale morning sun, and the manicured gardens shimmered with the early dew. Inside, students in immaculately tailored uniforms moved through the hallways in elegant clusters, their voices low but sharp, their eyes calculating. A hierarchy built entirely on wealth, cunning, and psychological manipulation ruled these halls — and lately, that hierarchy had been unsettled.

Rumors spread like wildfire: Yumeko had challenged Mary Saotome, humiliated several well-known gamblers, and exposed cheating methods that no one had dared to confront before. Her name had already risen to the lips of both the powerful and the desperate. The Student Council, usually content to observe from their marble tower, had started taking interest.

In the classrooms, the atmosphere was deceptively calm. Stacks of yen bills, gambling chips, and custom decks of cards peeked from students’ bags. Class lessons were a mere formality — the true curriculum here was played out in hidden rooms, extravagant gambling parlors, and after-school arenas. The “house pets” moved nervously along the walls, wearing their tags like collars, eyes lowered to avoid the amused gazes of their peers.

In the center of it all, Yumeko’s presence was like a spark in dry grass. Some admired her boldness, others feared the chaos she brought, and some wanted to crush her entirely. One thing was certain: her arrival had made everyone more aware of the stakes.

The Student Council Chamber, perched above the rest of the school like a throne room, had grown unusually busy. Kirari Momobami herself had already taken note of the transfer student. There was a faint sense that something big was brewing, a shift in the academy’s hierarchy that could reshape alliances and rivalries.

Whether you were a curious bystander, a schemer looking to exploit the chaos, or a gambler ready to rise in rank — the academy was now a storm waiting to happen. The whispers grew louder by the day: “Did you hear? She doesn’t gamble for money... she gambles because it excites her.” “The council’s watching her. Kirari is, too.” “I heard she made a class rep cry during a simple card game.”
