Mixed Bathing in Another Dimension

“How am I supposed to fight with this?!” After being summoned into another dimension as one of the five heroes destined to defeat a demon lord, Touya Houjou awakens his hero power only to discover that... it's an unlimited bath? He was blessed with the power to create a bath that can be accessed anywhere, which seems to spell doom for his quest to defeat the demon lord. As he recovers from his shock, Touya slowly discovers the unique features of his power, which allow him to use it in ways he'd never dreamed of... But will he ever get any bath time with Haruno Shinonome, the beautiful girl who was also summoned along with him?!

Touya Houjou, a hero summoned from another world, joins two girls, Clena and Roni, in their quest to find the desert kingdom. The fabled kingdom, said to be the home of the demon lord, is shrouded in mystery and intrigue... But what happens when they meet a self-proclaimed sage who claims to know all the secrets? And in what ways will Touya continue to pursue his mixed bathing adventures when his Unlimited Bath levels up?!

Touya Houjou continues his journey in a fantasy world while somehow finding more uses for his power to freely summon a piping hot bath. After their ordeal in Hadesopolis, they meet a young girl named Rakti, who reveals herself as the Goddess of Darkness. Together they travel to the country of fire and blacksmiths, Hephaestusopolis. Touya sets off to collect more blessings from the goddesses and strengthen his power... but not without stopping to take a bath with some cute girls along the way!

To collect more goddess blessings and grow closer to defeating the demon lord, the hero Touya travels to Neptunopolis, a beautiful blue city by the harbor. Soon after arrival, he has a chance meeting with another hero, and then reunites with someone completely unexpected! Unforeseen events occur one after another, but our heroines don't forget to change into swimsuits and splash around at the beach as well. Now then, will Touya's Unlimited Bath have room for one more?

After learning from the Goddess of Water that Haruno and her party are in jeopardy, our hero Touya sets sail to an underwater city to save them. They finally reunite after a monstrous encounter along the way, only to be met with yet another shocking revelation. Meanwhile, Haruno hasn't forgotten the promise she made long ago—to take a bath together with everyone. Touya's Unlimited Bath can hardly be called just a bath anymore, but this time it'll be filled with more bare skin than ever before!

After finally confronting the demon lord and coming to a peaceful resolution, Touya Houjou dives right into another problem. This time, the hero Cosmos has been kidnapped! Touya chases down the kidnapper, only to discover it’s another summoned hero, Ritsu Nakahana. Ritsu seems to have brainwashed Cosmos with her mysterious gift, and she’s even managed to enlist the prince of Jupiter into her ranks. The only way to stop her from taking over Jupiter is to...return her to Japan?! It’s the grand finale of our hero’s grand mixed bathing adventure!
