That Time I Got Reincarnated as a Slime sæson 2 (2021)

After Rimuru, who hosts the powerful dragon Veldora, has already befriended two Demon Lords and strengthened his power in the Jurassic Forest as well as his political and economic position within his realm, it was time for him to fulfill his promise to Shizu. So he traveled together with Ranga to a distant kingdom to take care of Shizu's former students there. These children were also summoned from the real world, but their magic is unstable and threatens to kill them. With the help of the fairy queen Ramiris and his own abilities, however, Rimuru was able to summon or create powerful spirits that assist the children in controlling their magic.
