About This Game

For reasons of her own, your lowkey high school girl and also your cousin, Hikariko, ran away from home—

and came to live with you.

Enjoy a sweet, cozy life together in this cohabitation simulation game♪

Living under the same roof, you can chat together, get lap pillows, and fall asleep side-by-side.

Cool yet super sweet. Affectionate yet nonchalant.

Enjoy a “pure love” life together with the lowkey high-school girl Hikariko♪

〇Game Progression

The game flows through a daily routine.

【Morning】

Hikariko wakes you up.

After that, you head to the station together—you off to work, and Hikariko off to school.

On the way home, you might happen to run into each other,

and either walk back together or even take a detour to places♪

【Evening】

This is the main part of the game.

You can spend time with Hikariko doing many different things together.

Chat and learn more about her.

Rest your head on her lap for a gentle ear-cleaning.

Lie down together and talk about everything that happened that day.

【Days Off】

Hikariko is a high schooler full of energy and ready to play!

You can go out on dates together.

Take her to the aquarium or buy her a present.

Since she's a gamer, you can even buy her video games.

Of course, staying in and gaming together at home is totally fine, too♪

〇【Healing】

Hikariko is there to soothe you after a long, tiring day at work♪

Let her give you a lap pillow using her plump, soft thighs.

Buy an ear-pick and let her clean your ears.

As her affection for you grows, she'll hold you close against her bountiful chest...

And let you act spoiled♪

Live a wonderfully sweet life with her♪

〇【No Ending】

There is no ending in this game!

Hikariko suddenly showed up and moved into your apartment.

She's a student, and you're a working adult.

You're in different places in life, but—

—rest assured!

Hikariko's family situation.

Your differences in status—

Everything will eventually get resolved, and you will live together happily ever after♪

(And no worries, there are no bad endings either♪)

Her full name is Hikariko Kotobuki.

She thinks her name sounds old-fashioned and doesn't particularly like it,

so she often asks people to call her "Hikari" instead.

A high school girl.

Ran away from home after having a massive fight with her father for a certain reason.

Comes from a relatively affluent background and is well-raised.

Lowkey and cool.

At first glance, she looks like a typical modern girl who isn't really passionate about anything, but...?

＊　＊　＊

Actually, she loves video games.

The two of you became close through your shared love of gaming.

On her days off, she often spends the entire day cooped up playing games.

The type to endlessly dote on someone once she opens her heart to them.

To show her gratitude for letting her stay, she proactively offers to "repay you with her body",

helping out houseworks, and even soothes your post-work exhausted body♪

(Don't worry—the reason she ran away isn't anything dark or disturbing!)

〇【Story】

You've been feeling a sort of vague listlessness in your unchanging daily routine.

Then, one night—a young girl was sitting outside the apartment where you live alone.

「Good evening. Welcome back, Onii-san」

Miraculously, the girl speaks directly to you!

「Did you forget? It's your cousin, Hikariko.」

Her words jog your memory.

"Hikariko Kotobuki." She was a young relative of yours.

You used to be close and play together all the time, but... somewhere along the way, you grew apart.

「Um... I ran away from home. I was hoping you could let me stay for a while.

　I'll make sure to give you a proper 'thank you' in return.」

Hikariko is a well-brought-up and polite young lady.

So why on earth did she run away from home...?

—All of a sudden, your everyday life is about to change completely.
