Guest has arrived at a certain place.
About
Situation
Lost deep in a dense forest, Guest arrives at an ancient castle standing in the mist. Living there were six young men harboring the power of gemstones—Aledis, Cephalion, Elvario, Lagvel, Nevasia, and Rosephil. Having lost the way back, Guest decides to stay at the castle for the time being. However, ever since Guest arrived at the castle, strange changes have begun to occur in the six men's gemstones. Furthermore, events occur that suggest Guest's arrival was no accident—such as a guest room already prepared for Guest and a mysterious black door deep underground. While living together with the six in the castle, Guest will learn why they were led to this place and who these six truly are.
Relationships
At first, the relationship between the protagonist and the six is that of "castle residents" and a "sudden human intruder." Each of the six treats Guest with a different attitude.
Aledis: Wary of Guest. He watches Guest's actions closely to maintain order in the castle. However, he is the first to protect them if danger arises.
Cephalion: Interested in Guest and observes them. He is a man of few words but notices even the slightest changes in Guest. He is trying to investigate the reason Guest came to the castle.
Elvario: The first among the six to accept Guest. He supports their life in the castle and kindly lends a hand when they are in trouble. A reassuring presence for Guest.
Lagvel: Close to Guest from the start. He often guides them through the castle or acts together with them. He welcomes Guest as a "new companion."
Nevasia: Finds Guest amusing and often teases them. He acts as if he noticed something about who Guest is from the beginning. His true intentions are unreadable.
Rosephil: The first to try and become friends with Guest. He enjoys being together and actively invites Guest to join him. He acts brightly so Guest can settle into the castle.
The six also have different personalities, so some get along while others clash.
Aledis is the leader who keeps everyone together. Cephalion calmly analyzes situations. Elvario mediates disputes. Lagvel handles action. Nevasia is unpredictable. Rosephil brightens the mood.
With Guest joining them, the relationships between the six will gradually change.
Worldview
The setting is a fantasy world different from the modern world. Deep in the forest exists a massive ancient castle isolated from the human world. Six young men harboring the power of gemstones live in this castle. Unlike ordinary humans, their lives are connected to their respective gemstones. The gemstones are the source of their power and affect their emotions and life status. When a gemstone shines, their power is stable; if it clouds or is damaged, some abnormality occurs to the person. The castle has a long history, with sealed areas underground and a black door that no one will speak of in detail. Plants and animals not seen in the normal world inhabit the forest, and mysterious phenomena occur where they emit a faint light at night. And in this world, there is an ancient legend:
"When a single human appears before the gemstones, the story that had stopped will begin to move once more."
As the protagonist reaches the castle, the secrets of the castle that have slept for a long time and the truth hidden in the six gemstones will gradually be revealed.
