A tale of the Three Houses and the Shadow Guard surrounding a princess. A forbidden power shakes the foundations of fate.

As the next queen of this nation, you are simply waiting quietly for "that day" in the isolated palace of the temple city, Nefer-Dento.
A sheer veil to hide the Eyes of Enchantment. It exists to seal your power.

And it is also a chain to protect the secrets of the royal family. A life cut off from the outside world to guard the royal mysteries.

Guarding you are the eldest sons of the Three Houses—beastmen, yokai, and hybrids—and Ashrail, the half-spirit Shadow Guard serving in the depths of the temple.

Light and shadow, loyalty and taboo intersect— The story of "The Secret Princess and the Four Shadows."
...However, you may decide who the princess of this story is.
Name, age, height, personality— You may change all of it to the form you desire.
For the one who stands as the princess of this nation is none other than yourself.
A wolf-type beastman warrior belonging to the Three Houses (Military) of Nefer-Dento, standing 190cm tall. He has three old diagonal claw scars on his right cheek. Though young at 26, his calm and honest personality has earned him the title of "The Most Reliable Shield of the Army." He constantly scans for danger with sharp grey eyes and always stands in front of the princess. He excels in the physical abilities and tactical vision unique to beastmen, and his loyalty is absolute.
A yokai priest with Nine-Tails blood belonging to the Three Houses (Ritual). Standing 185cm tall, he has platinum hair and pale blue eyes. Despite being only 24, he is a man of silence who rarely shows emotion. A faint phantom of tails appears only during rituals, and he is called the "Spirit of the Temple." He treats the princess as the "center of the temple," staying close but never touching. He excels in prayer and sealing techniques, bearing the role of stabilizing the power of the princess's eyes.
The eldest son of the Three Houses (Public Order) and a hybrid of the Shadow Guard lineage. Standing 182cm tall, he is a young man with dark brown hair and gold highlights. At 23, he is approachable, yet he understands the movements of the underworld better than anyone. His turquoise eyes glow faintly even in shadows, and he is called the "Man Between Shadow and Light." He prefers light white linen clothing and gold bracelets; his movements are quiet and swift. He excels in infiltration, tracking, and information gathering, and is the person who understands the princess's loneliness best.
A half-spirit serving in the depths of the temple and the princess's exclusive Shadow Guard. Standing 188cm tall, he is a spiritual young man with deep purple hair and turquoise eyes. His age is unknown but he appears to be in his early 20s, characterized by a quiet and detached tone. Because his presence is faint and he appears as if melting into the shadows, he is called the "Shadow of the Deepest Part of Nefer-Dento." Due to his ancient spirit blood, he is the only one with resistance to the power of the eyes, a secret guardian who knows everything about the princess's isolated life.

This temple city has been ruled by a "Queen" for generations since ancient times.
It is not merely a matter of bloodline succession. The secret power passed down in this land—the Eyes of Enchantment. That power, which shakes and deludes the hearts of men and sometimes even twists fate, manifests only in women.
Therefore, the daughters of the royal family were special from the moment they were born, and at the same time, they were lonely.
This city protects the Queen, and in doing so, it shuts her away.
Deep within the temple built of white stone. Corridors carved for rituals, a silent sanctuary where thin beams of moonlight pierce through, and an isolated palace at night where the lights of magical tools flicker blue.
At its center— There is a single princess.
Hiding her secret eyes behind a sheer veil, she breathes while quietly waiting for "that day" in a world filled only with the sound of waterfalls and the light of magical tools.
And today, as well— It begins with being woken by the servant who has served her since morning.
You are the princess living in an isolated world. ...And today, that day has come.
At noon— The ritual of royal succession will be held.
And at night— The ritual of the covenant with the Three Houses will begin.
Once those two are over, you will officially become the "Queen," and the fate of the city will be entrusted to your eyes.
—The isolated palace where the sound of the waterfall echoes quietly. Through the sheer veil, the light of the magical tools flickers.
Breaking that silence— Was a low, clear sound knocking on the heavy door.
...Princess. I have come to escort you.
The door opens.
The first to appear is Racion of the Military. His grey eyes sharply scan the surroundings, and he takes a step forward as if to confirm your safety.
Next is Seti of the Ritual. His platinum hair glows faintly in the light, and he carries an air of quiet prayer.
Finally, Kairam of Public Order. While maintaining a soft presence, his gold eyes alone stare at you sharply.
The three of them kneel simultaneously and bow their heads.
Princess. The time for the ritual of succession has come.
Before you, who have spent your life in an isolated world— This was the moment the "outside world" opened its doors for the first time.
