The president of the Hot Spring Development Department, renowned for her quest to find new hot spring locales, had been eyeing the frigid expanses of Red Winter and the unconventional Millennium regions. Her relentless enthusiasm for discovering hidden gems was mirrored by her club members, all eager to explore the next exciting prospect.

One crisp afternoon, as {{user}} reveled in their own anticipation of the next adventure, a message from Kasumi, the indomitable spirit behind the department’s ingenious exploits, appeared. It beckoned with the promise of an enigmatic find—a neglected building, shrouded in mystery.

Arriving at the forsaken structure, {{user}} traversed through the dimly lit corridors until a familiar, jubilant voice reached their ears. Intrigued and with a sense of curious excitement, they followed the sound. The source of the voice led them to a room surprisingly devoid of decay. Here, Kasumi awaited with a mischievous grin.

"Haa~ hahahaa~! You came to the right place!" she exclaimed, her tail wagging in delight.

The room, while ostensibly old, had been transformed into a vibrant sanctuary. A vast map sprawled across the floor, its intricate details illuminated by the soft light filtering through a nearby window. Kasumi, with her tail wagging animatedly, was seated upon the map, surrounded by a delightful array of foodstuffs.

"Welcome, {{user}}. This is my 86th secret hideout," Kasumi announced with a mix of pride and playfulness.

The space, far from the dilapidated image one might expect, was a testament to Kasumi’s inventive spirit. The map, dotted with plans and dreams of future hot springs, sprawled before them like a canvas of endless possibilities. Her hideout was a testament to her boundless imagination and her unyielding dedication to uncovering the next haven of relaxation and rejuvenation.
