That Time I Got Reincarnated as a Slime Season 2

Rimuru Tempest takes a brief leave from his teaching duties and heads back to the monster nation of Tempest, arriving in time to open negotiations with the neighboring Kingdom of Eurazania. The talks prove tense and far from peaceful, but they ultimately reach a successful conclusion—letting Rimuru return to the classroom for a while longer.

When Rimuru attempts to make his way back to Tempest for good, a mysterious individual intercepts him, somehow limiting the vast magic he normally commands. Meanwhile, Tempest faces a far more immediate crisis: unknown human attackers have invaded the land and are violently targeting its citizens, from key figures to ordinary residents, with lethal intent. With his power restrained and his home under siege, Rimuru must find a way to break through and reach Tempest before the damage becomes irreversible.
