That Time I Got Reincarnated as a Slime: Visions of Coleus

Having successfully rescued the children he was teaching in the Kingdom of Engrassia, Rimuru finds his time as an educator drawing to a close. Just as he prepares to move on from this chapter of his life, Yuuki, the Grandmaster of the Free Union, approaches him with a new and urgent request. He asks Rimuru to investigate the escalating struggle for the throne in the Kingdom of Coleus, a nation strategically nestled between Engrassia and the Holy Empire of Lubelius. Accepting the mission, Rimuru slips into the kingdom under the assumed identity of "Satoru" to uncover the truth behind the political unrest. What begins as a straightforward inquiry into a royal succession dispute quickly reveals itself to be something far more dangerous. As he navigates the treacherous landscape of Coleus, Rimuru discovers that the kingdom is not merely torn apart by rival claimants vying for power. Instead, the entire conflict is being manipulated from the shadows by a sinister web of schemes woven by demons and vampires. Now operating deep undercover, Rimuru must untangle these dark machinations before the kingdom falls completely under their control.
