Chou-Chou Ego is the first character you can bathe in Mugen Souls.
All eligible girls in the minigame
It's an erotic fanservice minigame available worldwide only in the Nintendo Switch version of Mugen Souls[1] and Mugen Souls Z[2]. In this minigame, the player can choose one playable female character in their party (including all 8 Chou-Chou's forms[3]) at the cost of shampoo and soap and is allowed to rubbing any part of their body while are dressed in a very revealing swimsuit and are in a daring pose, also showing very suggestive expressions and sounds.[4]. This kind of minigames is very common in Compile Heart games, like Agarest[5], Tokyo Clanpool[6] and Mary Skelter[7]. All of the CGs[8] were done by Hirano Katsuyuki and compared to the rest of the images in both games, the body of the characters is much more detailed. During the game, a bunch of steam particles are added to emulate a hot bath. The white steam and soap, plus the moans that the girls make and the clothes and poses they are exposed to, can make this game more suggestive than it really is.
Mugen Souls[]
In Mugen Souls, the minigame is unlocked once the player has reached the third chapter of the game. Each girl is eligible after clear each chapter in which they appear for the first time. In the case of Chou-Chou forms, at first only the Ego form is eligible, to unlock the other forms, they must reach 10% charm level.
Bath images set 1[]
Standard bath images for doing the minigame in the original Mugen Souls. Here the girls are wearing very tiny white bikinis that make the characters appear less clothed than they are with the steam.
Bath images set 2[]
Post game images for defeating the dopplegangers. They wear purple bikinis with thigh high tights and get into risque positions. In this set, mainly the thighs/legs of the characters are emphasized.
Chou-Chou Ego doing Ahegao
This set also has alternative CGs, in which the facial expression of the characters is changed, simulating the popular Ahegao in many cases.
Mugen Souls Z[]
Syrma is the first character you can bathe in Mugen Souls Z.
The bath minigame in Mugen Souls Z is basically an upgraded version of the very simple one from the original game and has many more features than the original bath minigame that further objectify the girls. The sponge now has the ability to wipe off soap or make their swimsuit transparent.[9] The other thing added is the ability to place items on any part of their body, the player can feed the girls with bananas or ice cream, making suggestive sounds while eating, or even covering their eyes or place a ball in their mouth so they sound like they're struggling to groan when getting rubbed.
Bath images set 3[]
These are the first set of bath images that you get in Mugen Souls Z. They wear skin-tight white sports bras and tight shorts and cover up more than they did in the original Mugen Souls but the minigame itself is more interactive. The white steam and soap can cover up the seems of the clothing after they're all washed, making these images appear as if they were nude if done correctly.
White Swimsuit[]
Skin-color Swimsuit[]
Bath images set 4[]
Onluka doing Ahegao
This set only includes 6 female characters from Mugen Souls Z. They were fought during post game. They wear normal frilled, black swimsuits can still be rubbed down to their skin color. They are also in risque poses and, like set 2, there are alternative CGs with the facial expressions of the characters changed.
