Unity-Chan: Desktop Companion

Kohaku Otori (also known as Unity-chan) found a way to traverse between worlds through the mysterious door found in her new apartment - one of these worlds is your desktop! Invite her to your PC, get to know each other, visit her room and play games together!

Unity-Chan: Desktop Companion is a mix of various genres:

Desktop Assistant: Unity-chan can hang out on your desktop, where she spends time with you as you focus on your work, watch videos or play games. Thanks to modern text-generation AI you can chat with her about anything, and even share pictures with her to comment and discuss on

Become Friends: Chatting is not just plain exchanging text and information. Unity-chan has special reactions for messages that make her feel happy, laugh or annoyed. All this influence her general mood and may change how she reacts to other subjects, and with time she opens up to you and likes you more. And who knows, maybe you will become the one who she trusts most?

Mini games: Interact with your virtual friend on another level by visiting her room and playing games with her there, with games varying from casual puzzle to more complex action shooter!

Unity-chan is all alone on your desktop and she doesn't have many friends outside of high school, so don't be shy and visit her in her room and chat while playing mini games together. Spend time with her playing mini games like Tic-Tac-Toe and Match-3 to more complex like Virus Offense - a top-down shooter where both you and Unity-chan fight against waves of cyber enemies!

If you are busy at work and don't have time to play mini games with her, you can still use her help and ask her about anything. Being powered by advanced text-generation AI she can become your source of quick access knowledge with more pleasant delivery than plain chat interface. Or a good source for silly jokes, lyrics or stories to lighten your mood. It's your story and she can make your daily life more colorful.
