Kara

At the end of his previous existence, Sora found himself outside his own reality and reborn as a Risen on Earth.

Having found himself in a struggling, untrusting world long past its Golden Age, Kara wandered from settlement to settlement. He'd live with and get along with the lightless he'd meet, but they'd become cold or hostile to him once they'd inevitably find out he was Risen—a "Warlord." Before meeting Aurora and Mark, Kara spent much of his time wandering, friendless and listless.

Short for a teen, Kara has a boisterous personality. There's not much margin between him knowing your name and being your friend. He's not the sharpest bulb in the drawer—he left his brain cell behind in his original reality—but he's keen in ways that you might not expect.
