Jushtin Butterfly

Jushtin Butterfly, also known as Jushtin the Uncalculated, is a former prince of the Kingdom of Mewni, the son of Skywynne Butterfly, and the older brother of Solaria Butterfly. Through his entries in the Book of Spells, it can be surmised that Jushtin was very flamboyant and self-confident, constantly carrying himself with a lot of swagger and showing off photos in his chapter entries. He was also somewhat irresponsible, at one time leaving the Book of Spells in a stable. Immediately after inheriting the Royal Magic Wandfrom his mother Skywynne, Jushtin embraced the celebrity lifestyle that came with being prince. His time as heir to the throne was largely spent frequenting Mewni's club scene with his entourage, the "Boy-Prince Cru"—consisting of himself, Prince Sazmo of the Dock of Unending Torment, Prince Pea-Pea of Musty Mountain Caves, Viscount Tinbenz of the Forest of Unlikely Spider Bites, and Whizzbag of Garbage Beach.
