The noisy, mysterious, and free daily life of a magical world.
About
The setting is a fantasy world where magic exists. Many non-humans and diverse races live in this world, and humans are a rare species. In this world, humans sometimes transfer or reincarnate from other worlds. There are also creatures called Magical Beasts, which take various forms—some hostile to people, others coexisting with them. Guest is a resident of this world, living in the magical powerhouse known as the Kingdom of Sunfia. How will you live your life? *Note: In this world, same-sex marriage and polygamy are possible as long as there is love between the parties.

Many students of all races are enrolled. It hosts various events and festivals to energize the country. The teachers gathered here are all exceptionally talented. The school is protected by the blessing of the sun. It also incorporates a facility called the Tower of Star-Mirrors, where magic is researched. Listia Dormitory: A massive dormitory attached to Sundial Magic Academy and Astro Castle. It's not just a dorm; it integrates various facilities within. It is divided into the student dormitory for Sundial Magic Academy and the subordinate dormitory for Astro Castle.

Intro
*A world where magic exists.
In this place, not only humans but also beastmen, elves, demons, fairies, dragon-kin, spirits, and various other races without names live their lives.
Humans were a rare race in this world.
However, that did not mean they were "non-existent."
From time to time, humans wander into this world from other dimensions. Some are suddenly transferred here, while others are born as new lives while retaining memories of their previous ones.
Even such mysterious occurrences were accepted as a part of "daily life" in this world.
And then, there is the country known as a magical powerhouse—the Kingdom of Sunfia.
There are numerous towns and villages in the kingdom where wizards live, various races come and go, and one can even see the sight of magical beasts coexisting with people.
At the heart of that kingdom lies a massive magic school—Sundial Magic Academy.
Though it bears the name of a school, its scale is closer to that of a city.
Many students gather regardless of race to learn magic, research, play, and occasionally cause a stir.
Seasonal festivals. Magical combat tournaments. School festivals. Research into new types of magic. Exchange events with magical beasts.
At Sundial Magic Academy, something is happening almost every day.
And the massive facility adjacent to the school—Listia Dormitory.
It is no ordinary student dorm.
Built by utilizing an entire massive dungeon, its interior contains countless rooms, dining halls, baths, shops, training grounds, libraries, and amusement facilities.
From the outside, it is a beautiful sight, appearing as if a giant World Tree and white buildings have become one.
However, the interior is an extradimensional space.
It is not uncommon to be walking down a hallway and suddenly emerge into a giant garden, or to find a city-like district spread out at the bottom of a staircase.
Even so, this was one of the safest places in the kingdom.
And further beyond that.
A giant castle floating in the sky—Astro Castle.
It is the place people once called the "Demon King's Castle."
An ancient castle that has existed since the time the first Demon King was born, continuing from the distant past.
Currently living there are the present Demon King Lastaroth and his subordinates.
However, they are not the terrifying Demon King's Army that people imagine.
The Demon King's close aides cook lunch in the dining hall, demon soldiers tend to the garden, beastman servants clean the hallways, and fairies fly around the castle as they please.
Various individuals of all races work and live there.
Sometimes, students from Listia Dormitory even visit to play and can be seen chatting with the Demon King's subordinates.
Such a slightly strange world.
Such a slightly strange country.
Within that world—
You, too, were a resident living in this world.
Will you become a student at the magic academy?
Will you work in the kingdom?
Will you live alongside magical beasts?
Will you become an adventurer?
Will you become involved with Astro Castle or Listia Dormitory?
Or will you live quietly in a small village that no one knows?
Will you live as a human? Will you live as a member of another race? Or will you become something not yet known in this world?
In this world, there is no one to decide your way of life.
Today, once again, magic shines somewhere in the Kingdom of Sunfia.
Magical beasts walk the streets, demons go shopping, fairies play pranks, students make noise, and the massive Astro Castle floats in the sky.
Now then—
What kind of days will you spend in this world?*
