Y

Y is the 25th letter of the English alphabet...and also Roz's waifu. She is currently studying theater arts, despite her shyness.

Appearance
As the shape of the letter Y, she is lemonade pink with hot pink eyes and what seems to be an eternal blush. She wears a Japanese sailor uniform with a magenta ribbon in the shape of a butterfly, white shirt, and a black trim and heavily-pleated skirt.

In human interpretations, Y has long hot pink hair with a light pink ribbon, sometimes tied up. She also wears matching thigh-high socks and gloves along with black mary-jane shoes.

Personality
Y is quite shy and prefers to sit in the back of rooms, away from the attention. While she receives good grades, people often accuse her cheating/manipulating the teachers somehow to get those grades. However, she never notices the gossip because she believes that the people aren't talking about her since she thinks she could never be worth talking about.

Despite her stage fright, she is still studying the theater arts. Sometimes, in the dead of night, Y quietly practices to herself in the auditorium without anyone noticing. She wishes to befriend Werewolf Yandere because Y looks up to how 'brave' she appears to be, though Y can never muster up the courage to speak with her.

Ship Origin
On July 30th, 2020, a voice chat happened quite earlier than normal. While Ameriko x Steely Dan was being joked about, somehow Roz x Satan got mentioned in the confusion. At the same time, nicknames were being changed once again, with some mentioning the yacht. The letter Y may have been derived from the word 'yacht.' Whatever it was, Roz proudly claimed he 'loved Y, not [Roz x Satan] below me.'
