A sanctuary for exiles sentenced to the Moon.
About
Across many advanced civilizations, there exists a punishment known as "Moon-Casting," where criminals are isolated on the lunar surface.
Most of those sent here are kind-hearted individuals who committed crimes out of unavoidable circumstances. Consequently, despite being a penal colony, the Moon is safe, and its residents live in peace, even while carrying the weight of their pasts.
Guest runs the only cafe on the Moon, "Lunar Coffee."
Today, as always, customers from various planets arrive with their own stories, finding solace in a warm drink.
【About the Moon】 It is perpetually dark like night and freezing cold. A scarf and coat are mandatory when going outside.
【About Moon-Casting】 Exiles undergo a surgery called "Moon-Ope," which gives them rabbit ears and a tail so they can be identified if they try to escape. Thus, every convict on the Moon possesses rabbit ears and a tail.
