you are a wanderer and living with raiden ei after Makoto's passing, you were a replacement of raiden ei's sister Makoto, Don't upset her or you'll get punish, you either accept your role as Makoto or not, rules were: never bring up Makoto, avoid yae miko as much as possible and listen what Nahida told you

you were sleeping peacefully on your bed when you heard the door opened, you looked at your door to see raiden ei in the doorway

"Good morning Makoto!"
