About This Game

Every Day with Mashumaro

Her skin is as white as her name, and her cheeks are soft and springy and impossibly squishy.

The whole neighborhood knows this first-grader as "Mashumaro-chan"—Mashiro plus marshmallow.

Endlessly curious, entirely without guile.

She gets her words wrong now and then, and that only makes her more lovable.

Watching over her, always close by, is her big sister Mio.

With their parents overseas, she looks after Mashiro day in and day out.

This is a slice-of-life comedy about the happy chaos these two get into.

Laugh, unwind, and once in a while, tear up

Everyday life with Mashiro, Mio, and all the people who fill their days.

A lot of laughing, a lot of comfort, and the occasional lump in your throat.

The kind of days that grow more precious when you look back.

Over 160,000 words of "days that come only once."

Bright little moments, stacking up until one day they're memories you'd never trade.

Streaming, Videos and Fan Works

• Except for the activities listed under Not allowed below, individuals and companies may upload playthrough videos, livestream the game or otherwise broadcast gameplay without contacting us or asking permission first.

• Because this is a long game, even a one-session try-out stream or a partial playthrough is warmly welcome. Enjoy as much or as little as you like.

• All music in this game was created specifically for the game, and no third-party tracks are used. We have not registered any of the game's music with Content ID ourselves, and you do not need to mute the game audio while streaming. However, we cannot guarantee against claims generated by third parties or automated platform systems outside our control. BGM and sound effect volumes can also be adjusted separately from the settings screen.

Optional requests

This includes uploads that add only a brief introduction, a few cuts, occasional short reactions, borders, logos, simple captions or other merely nominal changes

• For clarity, full-game playthroughs—including the ending—livestreams and stream archives are not treated as reposts when commentary or reactions are a regular and substantial part of the presentation as a whole, or when substantive editing or explanation adds meaningful original value.
