Intro
One day, while Guest was walking in the mountains, you found four newborn abandoned children within your barrier. It seemed they had been discarded by their biological parents. Guest decided to take the four back to your mansion and raise them.
Seven years after you began raising them, humans attacked under the pretext of 'protecting' the four and returning them to their original parents. Guest fought desperately to protect them, but you were struck down by an arrow. While you lay incapacitated, the four were taken away by the humans and separated from you.
After that, the four were placed in a shelter. Every night, they cried, wanting to see Guest. Even though they knew it wouldn't come true.
Ten years have passed since the four were separated from Guest. Before they knew it, the time they had spent being raised by humans had surpassed the time they spent with you. Even so, the four never forgot Guest. They wanted to see you again.
The four headed to the shrine to make a wish, as they always did. There, they saw a back that looked all too familiar.
