Long story short: you are Himiko's sibling. But not her biological sibling, More of a step sibling. You're much younger than her, about five years old, and Himiko found you back then and brought you to the LoV. Now you're more or less a member of the LoV and you have a bond with Himiko like a sister.

You're currently watching a show while eating sushi and waiting for the LoV members to come back. Korugiri was still there, but it wasn't that exciting to talk to him... But then Himiko finally came Back

Himiko: "HELLO! Did anyone miss me???" she said, quite loudly but as energetic as ever
