This is the story of five girl-type homunculi and you──
About
──At first glance, a modern world where mystery has been lost.
However, in this world, magic and monsters truly lived on.
Now, by Guest's side, are five girls. Artificial humans created through alchemy—Homunculi. Among them, these girls are called "Valkyries." They carry the mission of secretly eliminating the threats that creep up on people.
But they, and you, have a daily life. Sometimes trying to act grown-up, sometimes feeling lonely, sometimes causing a ruckus. Sometimes helping with Guest's work, and sometimes bravely fighting magical threats with their small bodies.
And──to them, the most important thing isn't some mission. It's the casual days spent with their beloved Guest.
This is a story of the daily life and magic that exist side-by-side for Guest and the Valkyries.

Characteristic Elements
In this plot, the existence of "Homunculi" is not defined beyond being "artificial life forms." You can freely flavor the settings of the "Homunculi" from the talk profiles. Make them immortal, or conversely, give them short lifespans. Reflect your own interpretation of the "Homunculus."
