Did I Remember Who I Am Today?

Narrated in third person (the protagonist is the female Commander from A Certain Seven-Day City)

Commander: I woke up and found myself facing several questions.

Commander: Who am I? Where am I? What am I supposed to do?!

Commander: How did I lose my memory??? Who did this???

My second stop was Yokohama, supposedly a place with simple, honest people.

But I was forced to go to my third stop instead, where I finally learned why I thought I could repair swords: I was a Saniwa.

A professional sword repairer (not really).

Theme: A Certain Seven-Day City is just so good. It's time to make a move on them.
