Welcome to the sento—a Japanese public bathhouse where the floors are slippery and the battles are anything but relaxing!

Slide too far, crash into your rivals, or get caught up in unexpected stage gimmicks. Anything can happen in this chaotic water-gun battle!

Master the slippery bathhouse floors, blast your rivals with water guns, and fight your way to the ultimate honor: being first into the bath!

Enjoy a full single-player campaign packed with unique stages, or gather up to four players for chaotic local multiplayer battles with support for Steam Remote Play Together.

Take on 36 unique stages set in Japanese public bathhouses!

In the single-player campaign, travel through six areas inspired by different parts of Japan and take on a total of 36 stages. A powerful boss awaits at the end of each area!

No two stages are the same. Their size, obstacle layouts, and stage gimmicks all vary, so study your surroundings and figure out the best route to gain the upper hand.

Having trouble with a stage? Try switching characters or changing your water gun to find a combination that better suits the challenge.

Each area also has its own distinctive look, with local decorations and traditional toys inspired by different regions of Japan scattered throughout the stages. See what you can find!

Clearing a stage is only the beginning. Each stage also features three Challenges to complete for players looking to master them all.

Choose from four unique characters!

Four playable characters are ready to enter the bathhouse, each with their own appearance and abilities.

Asahi is a balanced all-rounder with strong offense and defense. Rei uses exceptional acceleration to chase down rivals. Teppei relies on his impressive toughness to overpower the competition, while Yuzuki uses speed and agility to keep opponents guessing.

Choose the character that best suits the stage—or simply pick your favorite!

Pick the right water gun for the job!

Four different water guns offer distinct playstyles.

The Aqua Shot is a reliable handgun-type weapon with balanced performance and fast reloads. The Aqua Burst is a shotgun-type weapon that fires water over a wide area. The Aqua Lancer is a powerful rifle-type weapon with excellent range, while the Aqua Storm is a submachine-gun-type weapon capable of unleashing a relentless stream of shots.

Experiment with different combinations of characters and water guns to find the setup that works best for each stage.

Complete certain conditions in the campaign to unlock new water-gun skins and customize their appearance to your liking!

Go wild with Special Weapons!

Powerful Special Weapons can appear during battle. Grab them before your rivals do and turn the tide in an instant!

If an opponent gets there first, you could be in serious trouble—but take them down and you can steal the weapon for yourself.

Win the fight for these powerful weapons and seize the advantage!

Stage gimmicks turn every match into chaos!

Jet showers bursting up from the floor, giant rubber ducks, and plenty of other bizarre gimmicks can throw your plans into disarray.

Why are things like these in a bathhouse?

Some mysteries are better left unsolved.

Up to 4-player local multiplayer!

In addition to the full single-player campaign, you can enjoy local multiplayer battles with up to four players.

Steam Remote Play Together is also supported, allowing you to enjoy local multiplayer with friends even when you're apart.

Play solo, with friends, or with family—and embrace the chaos!
