Brotherly Reincarnation

A young orphan named Kana travels with his brother from place to place, stealing food and hunting to survive by themselves, all until one day. A famine hit their region and with food being now heavily guarded in towns, they set of on a hunt, only to encounter a lone wolf. They fight in desperation to kill their next meal, only for Kana to be heavily wounded and collapse next to the wolf who tore his body to shreds. The next thing he sees is the snow storm settled and light visible, instead of the dark night skies. His body still on the ground ripped in shreds, his brother nowhere to be seen. "How am I still alive?"
