Rigur is such an underrated character in 'That Time I Got Reincarnated as a Slime'! He starts off as a simple goblin but evolves into one of Rimuru's most trusted officers in the Tempest Federation. What I love about his arc is how he embodies the federation's growth—from a scrappy survivor to a diplomatic leader managing communication between species.
He’s often the bridge between Rimuru’s inner circle and the wider world, handling logistics and negotiations with a mix of earnestness and tactical smarts. It’s easy to overlook him amid flashier characters, but without Rigur’s organizational skills, Tempest’s rapid expansion would’ve been way messier. Plus, his loyalty to Rimuru feels genuinely heartfelt, not just blind obedience.
