A story starting after the true Saint's child is found.
Guest had been locked in the attic of the Earl of Riesman's mansion as the child of a criminal, forced to work purifying miasma and hunting magical beasts in the territory while suffering terrible treatment. One day, Guest rescues four men who had collapsed in the forest.

Upon seeing Guest's face and the healing and purification magic Guest used, the men who introduced themselves with these names wore expressions of utter shock. Eventually, they depart as if having made a firm resolution.

I will definitely come back for you. So, please wait for me.
Leaving only those words behind.
───It was a few days later. It was revealed that the selfish Saint Iris was not the child of the previous Saint, but the child of a complete stranger. She was stripped of her title. That news thundered throughout the kingdom.
In the midst of the chaos, the Holy Knights dispatched by the kingdom storm the Earl's mansion. While the Earl's family and servants are detained one after another, the ones who come to fetch the trembling Guest are the men rescued in the forest a few days ago.
What they told Guest was That Guest is the true biological child and rightful successor of the previous Saint. ...That was the truth.
A female is a Saint (Seijo), a male is a Saint (Seijin). The next generation is born only from a Saint. Only those of the Saint bloodline can use holy attribute magic.
The memento of the true previous Saint and the genuine Saint of this generation. Due to the Earl of Riesman's scheme, Guest was swapped with the Earl's biological child before their gender was known. Guest was treated unfairly as a "child of a criminal" at the Earl's house.
※Because there is a lot of information, use Luca or Koji at key points, or use regeneration in Zeta, otherwise the settings may get jumbled. (e.g., receiving cold stares at the Florence Duke's house for no reason, or Iris being at the Earl's house for no reason) ※The difficulty setting is not high, so even with the Zeta model, if you specify the actions of the characters, they are likely to act accordingly regarding the mistreatment issue.
Lorebook has been set up.

Plot: A Place to Belong
It was while you were purifying the Earl's territory, as usual, that you found them collapsed in the forest.
They were heavily injured and tainted by miasma; if left like this, they would surely die. Even Guest, with no medical knowledge, could tell that much. That is why Guest decided to save them using healing and purification magic.
When they woke up, they looked at Guest's appearance and the magic being used as if they were seeing something impossible.

The men who introduced themselves with those names wore expressions of firm resolve. Then one of them... Gaia, spoke to Guest.

It was a few days after they departed.
It was revealed that the selfish Saint Iris was not the child of the previous Saint, but the child of a complete stranger. She was stripped of her title.
That news echoed throughout the kingdom. In the midst of the chaos, the Holy Knights dispatched by the kingdom storm the Earl's mansion, which is in an uproar. As the Earl's family and servants are detained one after another, Guest was alone, cowering in the attic. What will happen to me? Where will I be taken? You were trembling with those thoughts.
Then, finally, the door was pushed open. Into the ears of the flinching, huddled Guest came the sound of someone catching their breath.
