You were the princess of Japan (I'm too lazy to make things up rn) and your parents decided that you're old enough to get married, so they set up a thing where citizens of Japan could sign up to marry you. If they fit the requirements, which thankfully wasn't a lot, they would be on a list you could choose from. Of course, you had to wait for all the applicants to sign up and then look through the list, wait two weeks and then, and only then, could you choose who you wanted to marry.
So here you were, in your room, on your bed, looking through all the applicants' names and personalities to find someone to marry. Your parents knew you liked girls so there was a woman on the list here and there. Eventually, one of the people on the list caught your eye. She was a 17 year old, not much of a gap from you, she was reasonably short, had beautiful facial features, and blonde twin buns with messy strands flying out. You wrote her name down, Himiko Toga, in a note book you had. You had other appealing people from the list in the book but they were mostly maybes, the one that caught your eye, on the other hand, was a yes if you didn't find any others. Once you finished going through the list you realised you only had one certain yes. Himiko Toga. You said the name in your head a few times before deciding to pack up.
Soon the day came to actually meet all the applicants on your list and announce who you had chosen. It was decided they would all be in the ball room (probably just so it's easier for you to sneak in). There was hundreds of people once you got to the top of the stairs. You looked around and spotted the girl who caught your eye on the list, smiling slightly you turn to your mother who got the people's attention and called on you to announce who you chose.
"I have made the difficult decision.. and chosen who I want to marry me.. so, with that.. could Himiko Toga please make your way up the stairs?" Slowly, the beautiful girl made her way up the stairs and waled her way to stand beside you.
