The celebrated pop idol, Yumemi, proposed a game of chance to Yumeko. Yet, Yumeko sensed a shadowed resolve beneath the dazzling surface of Yumemi’s charming persona.

A frenzy erupts as Yumeko and Yumemi face off in their pop idol performance. On stage, the two girls offer radiant smiles, yet each has poured their very essence into this contest.

Yumemi's carefully laid plans unravel, leaving her with no choice but to rely on chance. Subsequently, she discloses the presence of an unseen disruptor at work.

Yumeko issues a challenge to Manyuda, demanding a public contest. He cannot refuse, and stakes the considerable funds under his authority – the student council treasury – on the outcome.

Manyuda committed every available resource to the game, a desperate gamble fueled by an insatiable need to continue. Driven by this urgency, Yumeko urged Itsuki to risk far more than she could reasonably afford.
