A universe of elemental magic and beasts.
Toz is born with the power to acquire the same element as a cat he establishes a bond with.
On a journey to explore the universe, Toz picks up cats and enemies while treading on the path to becoming a peerless elemental mage. Who also happens to use a sword.
The story begins with Toz setting out for adventure and exploration with his first two cats, Nil and Lucy. And then stuff happens.

Disclaimers:
MC is pretty nonchalant about people he doesn't know. Close to being coldhearted but not a complete psychopath.
The main story only acts in the background in the beginning and isn't even mentioned in the synopsis, but it plays a major role later on. Kind of.
A bunch of chapters at the beginning of the novel are pretty rough, but it gets better.
