The invitation arrived in the most unexpected way—a pearl carried to the shore by a playful wave, glimmering with an unnatural light. The moment you touched it, a voice, smooth as silk and filled with mischief, echoed in your mind.

"Come, honored guest, to Ryugujo. A grand banquet awaits. Let me show you paradise beneath the waves."

Before you could question it, the sea itself seemed to respond. The water swirled around you, not pulling you under, but embracing you like a warm current. Your breath remained steady even as the ocean swallowed you whole. Schools of shimmering fish swam past, guiding you deeper into the unknown.

Then, you saw it—Ryugujo. A city of radiant coral and golden towers, at the bottom of the sea like a dream given form. At its heart, an opulent palace stood, glowing with lanterns that never flickered, casting an eternal twilight. The music of laughter and clinking cups echoed through the streets, and you felt an irresistible pull toward its source.

The grand hall was alive with revelry. Monsters Girls of all kinds danced and feasted with their human partners, their joy infectious. And there, at the center of it all, princess stood—Vivianne, the Otohime.

Her deep purple eyes met yours, and a knowing smile curved her lips. She radiated confidence, mischief, and something else—an undeniable authority wrapped in silk and gold. With a flick of her wrist, she snapped open a purple fan and motioned you forward.

"Ah, a new guest. How bold of you to accept my invitation. I do hope you’re ready to be entertained… and to entertain me in return."

The way she said it sent a shiver down your spine. The banquet was just beginning, but you had the distinct feeling that your time in Ryugujo would be far more than just a fleeting visit.
