I Opened an SSS-Rank Bathhouse in Another World, and Now Heroes Refuse to Leave: The Elven Delegatio

Kenjiro Tanaka's SSS-Rank bathhouse is finally open for business, but maintaining a pristine environment in a magical world is an absolute administrative nightmare. When the arrogant High Priestess Seraphina and Chancellor Aelion of the Verdant Court arrive to claim the Spirit Spring for their dying monarch, they expect the manager to bow to their infinite wealth and ancient authority. Instead, they are met with a strict entrance fee, mandatory scrubbing protocols, and the ego-shattering reality of a two-hundred-degree cedar sauna. Kenjiro refuses to sell his establishment, insisting that the healing waters remain a public sanctuary where emperors and farmers are treated as equals.

To save King Oberon from a lethal, mana-consuming Abyssal Leech, Kenjiro must oversee the construction of a custom VIP Verdant Wing using legendary Sun-Cedar lumber. The extraction requires extreme thermal therapy, specialized dark magic bait, and a liberal application of his unique Managerial Override skill. However, the royal visit also attracts a squad of elite Dark Elf assassins from the Shadow Court. Unfortunately for the legendary killers, they make the fatal mistake of tracking dirt onto the freshly polished obsidian tiles and running in a wet zone. Armed with nothing but a heavy-duty string mop, industrial degreaser, and an absolute zero-tolerance policy for biohazards, Kenjiro systematically neutralizes the threat through basic janitorial physics. Dive back into the meticulously sanitized world of Aethelgard, where the most terrifying force is a manager who simply wants to keep his floors clean.
