Isekai Saihate Onsen Kikou
異世界サイハテ温泉紀行
Aiden serves as a soldier in a kingdom and recalls a past life as an office worker who frequently visited hot springs to unwind. In this new world, his military duties prevent him from taking extended breaks, limiting his access to only local hot springs. The narrative starts when he discovers that the princess, Milka, shares his interest in hot spring visits.
