|Name Kanji||カイン Kain|
- "The younger brother was simply a part of his own soul... The me that was loved by everyone and by the world I used to live in. For I had already long since turned into one of those evil spirits, dragging out their existence in the wasteland."
One of the two characters in Seishin's book entitled: "Shiki".
In his story, the Earth had been frozen over and hardened up and down, many times over. The dark and gloomy sky hangs low, where the clouds and the Earth has the world beautifully divided into two. Cain has been cursed and exiled. When night comes he comes to a wasteland. His younger brother who had already been slain, that corpse should have been buried together with his grief. Yet tonight, it comes again; resurrected from its grave. Abel is a shiki.
Cain is an outcast. Everything he touched was ruined. Try as he might, he couldn't do anything correctly. When he drew water from the well it would turn to dirt. His younger brother was much loved. He was kindhearted and caring. His presence would bring smiles to everyone around him. Cain ultimately kills him.
For killing his younger brother he was exiled from his town, but his brother still follows him around.
In the story, it is said that Cain was cursed and exiled. In the story, Cain tills the land whilst his brother Abel is a Shepherd. Out of jealousy for his brother, one day in the Shepherds field, Cain killed his younger brother with a pitchfork and was banished from the lands by the people. Following him across the lands was his risen brother, and during that time together, Cain became a Jinrou.
Whilst travelling, Abel eventually admitted that he was actually waiting for Cain to kill him and seemed to be grateful that he was killed. After that, unlike how Shiki normally die, Abel just simply vanished into thin air like a ghost, as if he never even existed.
Once his brother had disappeared, Cain came to the realisation that he and Abel were in fact, the same person. Abel represented the happy, caring part of him which fit in with society. When he fell into despair and attempted suicide, that "Abel" part of him had been killed. This left him unable to be part of the human world, leaving only the wasteland of despair. The village drove him to despair, for which he creates the metaphor of being exiled. The wasteland represents the despair. As he tells Sunako, "All we have left to us is despair. Having been exiled from the human world, we can only keep walking across the endless dark wasteland."
