Game Details
Synopsis
Meet your love interest (nameable). She’s referred to you all her life as Oniichan (relationship changeable). Affectionately, you also call her your little Sister (also changeable)! You cohabitate in a small studio apartment. You’ll have to get along in this small area where you’ll spend a lot of time together. Through interacting with her, you build up a relationship that’s based on trust, friendship . . . and more!
Talk to her and find out her favourite topics, play video games, and take her with you on day trips. Through your actions, she can come to trust you more, and, of course, you can also build her sexual attraction toward you. But be warned! You can also lose her trust in you. Living Together! is a laid-back game intended to be played with one hand. Please enjoy this simple Oniichan game.

Developer Notes
Key Features
- Believably beautiful Imouto, rendered in high-poly 3D. She could be real.
- Fully simulated Imouto, with more than 50 variable psychological metrics like interests, mood, lust, sexual interest, and more. She IS real.
- According to my estimates, Imouto can adopt more than 30,000,000,000,000,000,000,000,000,000,000,000,000,000,000 (that’s 30 with 49 zeroes) possible personas. These personas are seeded so they remain believable.
- Build Trust and Attraction through a deep dialogue system and actions; lose her trust and sexual interest in you by messing things up.
- Spend leisurely days with your little sister, talking, flirting, bathing and potentially having sex with her (future update) — if she trusts you enough and is attracted to you.
- Get closer together, really…close…together.
- Be a creep and spy on her as she bathes or uses the toilet. Be careful; you might get caught!
- Beautiful “1K Apato” Apartment with day-night cycle.
- Energy, time, money, household management, and other systems were added and planned!Key Features
