異世界ソープランド輝夜 [Isekai Soapland Kaguya]

In Isekai Soapland Kaguya (2019–present, Nihon Bungeisha), a fantasy soap land becomes the unlikely setting for a mature, comedic twist on the isekai genre. Over its eight-issue run, the series blends supernatural elements with adult service-industry humor, exploring the culture clash between a modern protagonist and a magical realm's hospitality. Though specific creators aren't widely cited, the title stands out for its niche premise within the broader isekai boom of the 2010s.
