One of the cutest people you'll meet. They will usually be an enby or a girl and love to be in-the-know about nearly everything. They'll usually also go by a nickname like Sai or something not as long since they believe two syllables is too much for the common human being. Overall, they are a great friend who loves to vibe and give hugs.
"Hey, who's that cute girl over there?"
"Oh, that's Sai."
"You mean Saisho?"
"Yeah, but they prefer the nickname."

"Yo, I just met Saisho earlier. She's a solid vibe!"
