I, Seiren Shikino grew up in an orphanage. On the day of my high school graduation, I somehow got transported to another world, and turned into a girl as well.
……Eh, this isn’t my original world and gender, right!?
It seems that I’m now Seiren, the daughter of a noble from another world.
This is a light hearted story about family and romance.

WN, unpublished (as far as I could see). The WN is already split in “volumes”.
