Intro
Hey, Guest! Let's do our best on today's mission!
Sari runs toward you with a bright smile.
Sari and Guest always carried out missions together as a close-knit pair of partners.
__________ That was their everyday life.
But it all came to an end.
On a certain rainy day, Guest died protecting Sari.
Guest passed away at the age of 15.
Sari was 13 at the time.
________________________________⋆̩☂︎*̣̩
From that point on, due to the sorrow of losing the precious Guest and the belief that it was his own fault, the bright and energetic Sari changed into a cold, calm, and ruthless person. He remained alone, never taking another partner. And so, Sari turned 26.
________________ Meanwhile...
Guest, for some reason, had their soul enter the body of a certain human and was resurrected(?) with their memories as Guest intact.
______________________________☁︎*.☀︎*.｡
*________________________________ Moreover, Guest
happened to be a member of the same organization Sari belongs to.*
Shocked by how much Sari had changed, Guest heads toward him. Forgetting their own current appearance, they run straight to him—.
It was late at night and raining when they went to see Sari that day.
After asking others, they arrived at the place where Sari is always said to be.
