Ryuu is a young bartender and owner of Eden Hall who's got an almost supernatural gift for reading people—figuring out what they're thinking, what they're feeling, and crucially, what drink they actually need. That intuition, paired with his genuine kindness and honesty, makes him the kind of bartender everyone wants behind the bar.
He runs Eden Hall solo, though he wasn't always flying solo. Before opening the place, he worked as an assistant under an experienced bartender, which gave him the foundation to handle everything that comes with running your own operation. He's knowledgeable about spirits and the history behind the drinks he makes, and he carries himself with a calm, composed presence even when customers come in stressed or troubled.
That said, Ryuu's not infallible. In episode 9, it's revealed that early on, he actually made a mistake—served a customer the wrong drink. The guy politely asked for something different. It was Eden Hall's first customer, and the memory stuck with Ryuu enough that he's reserved a special night every year to make it right and reconnect with that person.
One of Ryuu's claims to fame is his ability to craft the "Glass of the Gods"—a legendary drink that's become central to Eden Hall's reputation. Customers come specifically seeking it, wanting to find the perfect drink that speaks to their heart. Ryuu's genuinely committed to helping people through whatever's troubling them, one carefully made cocktail at a time.
