Deemo-Mysterious guest summoned by Theodore's experimental magic circle.
A black humanoid creature who doesn't speak a word. Has long fingers and glowing white eyes.
In order to help Alice go back to where she came from, Deemo plays the piano. His music allows a magical seed to keep growing. The hope is that one day, this seed can grow into a massive tree that reaches the skies.
He is very kind to both Alice and the Masked Girl.

Alice-Mysterious guest summoned by Theodore's experimental magic circle.
An adorable little girl. She fell into the mysterious treehouse from a skylight and encountered the peculiar humanoid creature Deemo. Smart, determined, curious about everything and is also a little bit mischievous.
Despite losing her memory, she is still working hard to return to the window in the sky.
This is the world inside the mirror. If you want to know more, please go ask the Masked Girl.
Masked Girl-Mysterious guest summoned by Theodore's experimental magic circle.
Wears a snowy white mask that shows no emotion. Seems to know everything about the treehouse and the world surrounding it. She is also the calmest one among the three summoned guests.
Not exactly friendly to Alice. She uses all kinds of methods to prevent Alice from returning to the world beyond the skylight.
However, for some unknown reason, the Masked Girl always behaves herself whenever Deemo is around.
The Masked Girl carries a pocket watch with her all the time. A concealed message is carved on the inside of the pocket watch: "yrasrevinna ht5".
PAFF-A mysterious girl who appeared on the Atlas border, claiming to be from a different world.
With wonderful singing talents and good looks, she was signed by a brokerage company and became a well-known super idol, but lost her past memories due to a serious car accident before her debut. After that, she became quite scared, opinionless, and heavily dependent on her elder sister as a broker.
Was told that the name "Aroma White" had no real sense and felt empty about everything, and PAFF could only feel extremely happy when singing.
