Kai

Kai Young is a citizen of the Apocalyptic Realm, and has Julian Lason as a traveling buddy.

Like Julian, he grew up in a large family, but wasn't neglected by his parents (unlike Julian). It wasn't until he was 12 when he lost most of his family in a zombie raid. He escaped without getting any zombie's attention. He found Julian on the same day.

Since they both had nowhere to go, the two decided to roam the realm together, increasing their chance of survival.

Trivia
