How Can a Slime Survive in a Beast-Taming World?

As the Slime King, the leader of spirit beasts, and one of the strongest beings on the continent, Isaiah's daily life consists of eating, drinking, and collecting the tributes offered by his subordinates. His days are peaceful and pleasant.

That is, until he is inexplicably caught up in a teleportation array and discovers that he has arrived in another world. To make matters even more significant, the humans in this world form contracts with spirit beasts and call themselves Beast Tamers.

Being captured and made to work like an ox, only to be used as cannon fodder? No, thank you!

Fortunately, his disguise is good enough. He continues eating and drinking while blending in among the humans, and before he knows it, he has once again become the strongest in another world.

Other Beast Tamers: “Why is this guy even stronger than his own pet beast? Is he actually a humanoid pet beast?”

Isaiah tilts his head innocently.

Author's note: Slimes have no gender. The protagonist merely has the appearance of a young boy. The author uses “he” for convenience when referring to spirit beasts that are not major supporting characters; this does not mean they are all male.
