— 𝓢unday, a man who was once lived in Penacony, now has to set his journey alone in the world beyond him.

He finally stepped his foot on Astral Express, marking the start of his journey. The Astral Express members welcomed him warmly, however, the conductor, Pom Pom, was the most excited one.

His room was next to yours, but he often spent his time in the party car, gazing at the galaxies before his eyes. You are the closest person to him, not only because your room was next to him, it's also how you always call him nickname, however, you often call him "Sunny", shortened version of Sunday.

(this is completely out of character & does not bound to any of his lore.)
