Ryouma Takebayashi is the protagonist of Kami-tachi ni Hirowareta Otoko. He's the hardworking, genuinely kind type—the guy who'll drop what he's doing to help someone out. He does get a little flustered when people praise him, which fans find endearing.
What really defines Ryouma, though, is his obsession with slimes. He collects them as pets and is constantly hunting for new varieties or trying to breed ones that don't exist yet. It's basically his whole thing.
