Kaguya Houraisan
Kaguya is a divine lunarian who got kicked out of the moon for being a total diva and making an immortal potion. She stayed on Earth because she was too good for the moon.
My teacher said I was like Kaguya because I wouldn't stop talking about myself.
My cousin called me a moon diva because I wouldn't stop showing off.
My brother said I was too good for the moon because I wouldn't share my candy.
