The story of Persona 5 Royal, as seen through the eyes of an amnesiac girl who finds her way to Akechi as opposed to Ren. This is Sayaka's story and the events that happen to her while Ren and the Phantom Thieves go through their storylines.
This story features OC x Canon shipping ( Akechi x OC ) and platonic relationships between Sayaka and other existing characters. If you don't like this, just don't read it ... *shrug* This story has been crafted over nearly 4 years, and technically speaking, the shipping isn't outright romantic, as the two do not date.
May not be the best written, I'm better with Roleplaying stories than writing them alone.
