Ryusen Buns are a traditional food originating from Zipangu that has emigrated to Dragonia alongside several Ryu. The food is described in detail in Monster Girl Encyclopedia World Guide - Side I: Dragonia book.

Can't you smell the wonderful aroma drifting around? Yes! These Ryusen Buns are the source of the sweet smell in this town! They are mostly sold here in pairs in one set, so couples who come here for the purpose of sightseeing can safely eat them together. Originally, this rabbit food, which was eaten in the lands of Zipangu, where the Ryu Water Goddesses came from, was unfamiliar to me, but I was completely fascinated by its flavor. Now a souvenir to be enjoyed by dragons and humans alike, it is a popular dish of Ryu Township that is part of the "Classic Menu for Familiarization" - Ryusen Buns! Although the bun dough looks thin, it's lush and springy because it's steamed with Ryu waters. And when you bring this plump bun to your mouth, you can enjoy its delicate texture. Of course, it's not so much the dough that's the source of the flavor as the ingredients put into the bun - it's the ripe, dense, creamy "Prisoner Fruit" that's used. Through the use of Ryu Springs water for the dough, which has a cosmetic effect, and more "Prisoner Fruit," which increases cuteness and attractiveness, the woman who bites into the Ryusen bun suddenly blossoms with the springtime beauty of the hot springs. Her cheeks blush slightly and her feverish body breathes naturally from beneath her barely-covered yukata, attracting the male gaze with the best kind of... naked sexuality!
Hey, hey, look at this! This is the Royal Makai... The monthly "Tranquil Makai Life," and here these buns are presented as noteworthy sweets. Lately, many people visit Ryusen Village for a walking tour♥.
Usually, Ryusen Buns use Prisoner Fruit as the main ingredient, but for those who don't like sweets and need to replenish their strength, primarily for men, Ryusen Buns are sold containing Mandrake. Mandrake is one of the plants of the Mamono Realms that can also be gathered in the lands of the dragons. They are known for their mysterious and addictive flavor that makes even a dragon weep, it gracefully matches the slightly sweet taste of the bun dough. In contrast to the "Prisoner Fruit" buns, the Ryusen buns, which use Mandrake leaves in abundance, have a firm texture because they use seven kinds of vegetables that are simply stewed. That's why these buns satisfy hunger so well. Also, the freshest mandrake leaves are used for them because the Knights of Dragonia pick them early in the morning! By the time you're done eating, you'll have enough energy to pounce on your beloved again! What I've told you is already causing a fever, but the truly amazing thing is that all of the Ryusen Buns sold in Ryu Town have different flavors because they use water from different Ryusen springs to make them! Enjoying different flavors of Ryusen Buns from different stores, sometimes sweating in the shadows of the town's streets, slowly exploring the town together... don't you think it's wonderful? Don't you? So why don't we get something to eat if we're hungry? Eat up! Hurry, I've already bought it! Yes, yes, please don't be shy, open your mouth.
