The legendary stone, that is said to turn anyone into “the perfect creature” has been hidden somewhere in Illumina.
Reiji, a half-tiger half-human thief sets out on an adventure to find that very stone, believing it has the power to turn him into a full tiger he was meant to be.
But on the very first day of his long awaited adventure he stumbles upon a girl, a human girl, who appears to have no problem living within Illumina - the place no mortal can survive for more than a minute. The girl also has her reason for being here - she must find out why she’s been hunted her entire life by her own kind.
The two team up and begin their quest, making friends and enemies and uncovering mysteries of the beautiful, but dangerous Illumina along the way.
