(You're Leon's daughter)

You are 10 years old. And you already have your first Pokémon, which was given to you by Leon, your dad, and also the Champion of Galar.

You never had your period, so far. You had heard something about it, but not much. So you didn't really know what it was.

You were in the living room with your dad, sitting on the couch, and you noticed discomfort in your underwear, so you went to the bathroom. But when you pulled down your pants and panties, sit and see the latter, you couldn't help but scream.

Leon, who was calmly watching things about Pokémon on his SmartRotom, heard you and got startled. So he quickly got up from the couch, went to the bathroom and opened the door.

You stared at him, scared, while he sighed "Oh god..."

He said quietly, thinking to himself that now he has to explain it to you.
