How many GB is Mirror of the Phantom Maiden?

3 GB

That is less than the typical Role-playing (RPG) game, which needs about 6 GB.

Leave at least 9 GB free: games need headroom to unpack updates.

The figure is the storage Steam lists as required for this game, not a measured download.

To uncover her sister’s disappearance, the protagonist enters a strange school and explores a mirror world where day and night blur, spirits linger, and forgotten truths resurface.
