Rosado is a royal knight from Elusia who hails from a village near the Lake of Mystery. He describes it as a place of wonder where things like beauty are not restricted by "silly expectations that comes with stuff like gender." Eventually enrolling into Elusia's academy, he befriended Hortensia and Goldmary. When Hortensia was summoned by King Hyacinth, Rosado took Goldmary with him and followed him with Hortensia back to Elusia Castle. Though he was not officially made a retainer to Hortensia by King Hyacinth, Hortensia treats him and Goldmary as such. Rosado and Goldmary accompany Hortensia on her mission to steal the Emblem Rings from the Divine Dragon Alear. They are unsuccessful when they attack Alear's forces at the Firene-Brodia border and later during the attack on Destinea Cathedral. After the revival of the Fell Dragon Sombron, Hortensia spearheads an attack on Solm on her own, leaving behind both Rosado and Goldmary. After hearing word that Hortensia joined Alear's forces, Rosado and Goldmary pose as loyal Elusian soldiers and are able to steal the Ring of the Azure Twins. The two quickly head to the Azure Coast where they reunite with Hortensia and officially join Alear's army. Though Rosado returns the ring to Alear, they allow him to utilize its power in the ensuing battle. Rosado is cheerful, positive, and an optimist who lives his life to the fullest by pursuing all things cute and pretty. He appreciates external cuteness, but believes that cuteness starts within one's self. Having been raised in a welcoming village, Rosado is not deterred by the views of how one should be by others by things like gender norms. While confident in his cuteness and does brag about it on occasion, he enjoys seeing the "cuteness" in others and is not bothered when people shine in his presence. He actively encourages it in some who do not see it in them like with Lapis and Louis. Rosado has a talent for the arts and is a skilled sketch artist, able to quickly sketch a cute, flattering picture of Hortensia in a short session. He particularly loves drawing landscapes which evoke strong reactions in those who gaze upon them. This passion would become the foundation of his endings in Engage, where he becomes a renowned artist. Rosodo is a medium tall male with pale skin, cyan eyes, and curly light blue hair with two points at the top that look like cat ears or horns. His outfit consists of a black top with a diamond shaped opening in the middle, a purple skirt with a white and pink lining, pink leggings, black boots with one purple ribbon on the back of both, silver shoulder, hip, and knee guards, and a pink ribbon on the back of his head.
