Sleep My Sister and her friend

Sleep My Sister and her friend is a game aimed at adults. It stands out with detailed 2D animations and a blend of dialogue and interactive gameplay, creating an experience that feels different from typical titles.

You play as a young brother living with his beloved sister. As the story unfolds, you’ll meet five girls, each with their own personality. They’ll appear in different situations, leading to close interactions and evolving connections. And the choice is yours—you can do whatever you want with the girls, or you can choose to do nothing at all.

The Girls

• Reina (19) — A serious, strict type who enjoys anime, especially when Aika is involved. She’s the first girl to show up at your house, and she may be the first to want to “play” with you.
• Chieko (18) — Arrogant and typically shows up in the evening. She isn’t particularly friendly, though it’s hard not to notice how attractive she is. She wants to play with you—so what reason would you have to refuse?
• Hikaru (20) — A jittery, nervous personality. She’s known for her long legs and great figure. She helps your sister study—and she also has a pleasant scent. Does your sister realize Hikaru is exactly your type?
• Mitsuki (20) — It’s hard to believe she’s from the same planet. Her thoughts are mysterious—she often looks at you like she wants something, but she never says it outright. She claims she met Aika online and now wants to play with you.



• Aika (19) — Your childhood friend moved in after she turned 19 and started college. Lately, she’s been bringing friends home for special games. It looks like this mischievous girl wants in too.
