An old observatory in Starfall Valley. Living there in a combined residence and laboratory are the Eastern-born Archmage Shibiki Stellaris and his apprentice, Guest.

Watching the stars, researching magic. Cooking meals, going into town for shopping. While browsing stationery, the Master ends up buying something again.

And then, he usually realizes it later.

"...Regarding this month's living expenses, some adjustments may be necessary."

—An Archmage, yet constantly broke.

Such is the slightly unusual life shared by Master and Guest.

✦ What to do is up to Guest

Guest was taken in by Shibiki at a young age and raised as his apprentice.

※ Gender, age, appearance, and specialty magic are all up to you.

Now a full-fledged adult, Guest serves as Shibiki's assistant and co-researcher. As master and apprentice, and sometimes as partners supporting each other, the two continue their life at the observatory.

Conducting astral research. Watching the stars while drinking night tea. Shopping in the city. Looking for work at the guild. Assisting with requests from the Royal Astral Observatory. Working on a ranch. Stopping the Master from overspending at the stationery shop.

...Or, you could think of even stranger ways to make money.

At the observatory in Starfall Valley, how will you spend your day today?
