When we think of reincarnation, we often imagine new worlds, magic, dragons, and adventures. But what if you were reincarnated into another world, in a body that couldn't walk or talk?

- "What the… I can't walk or talk? Seriously?"

Most people would panic in such a situation, or even consider ending their lives in the hope of a better reincarnation. But Kai remains calm.

- "Well, whatever, this body is mine now."

As he explores this new world, meets new people, and builds a family, he gradually begins to settle in. But life is never peaceful. Kai finds himself embroiled in a series of incidents, from rampaging calamity-class monsters to kidnappings. He even gets engaged to a princess who can't stand to be near him. As if that wasn't enough, he has a host of people after him - some want to kill him, others want to save him.

Will he be able to survive in this new world despite his disability? Can he distinguish friend from foe? Only time will tell.
