Synopsis
This is a game in which you will make a naughty touch to “U10-chan”.
This is a “usable” game with an emphasis on practicality, created by borrowing the 3D model “U10 Body ver. 6.0.1” created by the manga artist and U10 creator, kaziya21.
You and U10 live together in a high-class apartment with a night view.
U10 is free to move around the room according to her own desires.
If you don’t do anything to U10, nothing special will happen.
Let’s touch U10 and lead her to the naughty things by easy operation of the mouse click!
– naughty motion, naughty moaning voice
Naughty motion materials by unimi_love, “echioto” by Momoyu Ugai! Voice materials are used!
You can enjoy U10’s realistic reactions!
– Horny gauge is equipped!
When you touch U10 sexually, U10’s horniness level will increase.
When U10 gets horny, she will start to masturbate, take off her clothes and insert your penis into her, and more.
– U10’s horniness can be seen visually!
When U10 feels pleasure, a pink effect will be displayed on the area.
The first one is a small sensation in the sexual zone, then it gradually increases and spreads to the head and deep inside the vagina, and finally reaches the climax.
– Vaginal and rectal cross sectional views show insertion!
When you insert U10 into her pussy or anus, the cross sectional view of vagina and rectum will be displayed.
Of course, you can also see how it looks like when you come inside her.
(“DPS cross sectional view” by Gal shop Tomngo is used.)
– Equipped with Bukkake system!
When you ejaculate on U10, you can choose between Nakadashi and Bukkake.
If you choose bukkake, you can ejaculate on U10’s body as much as you want until you run out of semen.

Editorial Review
Sitting firmly in the interactive 3D toy-simulator corner of the adult game space, this is a practicality-first experience rather than a story-driven one. Where much of the visual novel market leans on branching routes and heavy text, this one strips the format down to a single apartment, a single character, and a mouse cursor.
The most distinctive choice is the autonomy system. U10 wanders the high-class, night-view apartment according to her own desires, and the synopsis is explicit that nothing happens unless you initiate it. That passive-until-prompted design gives the room a lived-in, companion-sim feel instead of a scripted scene player. The horny gauge adds a progression layer, with her state escalating as you interact and a visual pink effect signaling her arousal, so feedback is readable at a glance. The production leans on borrowed but recognizable assets: the U10 Body ver. 6.0.1 3D model from manga artist kaziya21, motion materials credited to unimi_love, and voice work tied to “echioto.” Credited collaborators like these suggest a modular, craft-conscious build. The Voice and Music tags confirm audio is a core part of the appeal, not an afterthought. The APK inclusion is also a practical bonus, since mobile-ready builds remain uncommon in this niche, and the official English version lowers the barrier for international players.
This is best suited to players who want a low-friction, responsive sandbox with a reactive 3D character, and who value immediate feedback over narrative depth or branching choices.
Verdict: a streamlined, click-and-explore companion sim that does exactly what its title promises, with an unusually accessible multi-platform setup.
