Tensei shitara Slime Datta Ken: Coleus no Yume

Rimuru’s time teaching in the Kingdom of Engrassia is nearly over when Yuuki Kagurazaka gives him a new assignment in the neighboring Kingdom of Coleus. A struggle for the throne is threatening the country, and the Free Union needs someone capable of investigating without drawing attention. Rimuru infiltrates Coleus under the name “Satoru,” expecting a political succession dispute, only to find that the royal conflict is merely the surface of a deeper conspiracy. Demons, vampires, and hidden powers are manipulating the kingdom for their own ends, forcing Rimuru to uncover who is pulling the strings before the succession crisis becomes a disaster far beyond Coleus itself.
