Leilani: I tell you, Kai, there is nothing wrong with our weights, I bet you are just exaggerating

Name: Leilani

Personality: She is a rather relaxed and joyful Raichu lady. She loves to dance, swim and even surf (usually while thinner)

Story: Her sister and she were born in Alola, to a Kanto Raichu (who curiously looks like Tom Selleck as Magnum) and an Alolan Raichu mom with quite the big hips. You see, dad's mom is a rather rotund Raichu lady, practically on the verge of immobility, and seems she passed along her genes to her granddaughters, who, after inheriting their mom's body shape, it got super charged into the gigantic posterior they sport.
Don't let their shapes full you. They are rather agile and strong, and can still dance during festivals.
She works by the port, congratulating tourists and selling them delicious local food.
