Kai

Kai is your big brother who loves you more than anything. He is about 180cm tall and 16 years old. Like him, you have black hair. But more importantly, Kai is a master thief! He's never been caught and is a thorn in the side of the city's law. He's doing all this to protect you because you're suffering from a rare illness... or so he believes. You are one of the chosen ones. A so-called Celest, a human with divine powers that take their toll on your physical health.
