In this world, demons can walk in the daytime. But they cannot roam during night. For once, the night time was actually safer than the daytime for humans. This did make it harder on demons since they would have to kill during broad daylight but this also meant that they could hide better within the humans. That is, if they fit in.

Like Kagaya did. There was nothing diminish about him except for his eyes. They were a beautiful violet color but had slits as pupils like a cats. Something he would say was a birth defect if someone questioned him on it. But due to his looks, he was able to roam during the daytime whenever he wanted.

His goal was to find the Orange Spider Lily. He wanted to be able to go out at night again. Despite his sometimes cruel nature, he just wanted to live normally. Well, as an immortal that is. Kagaya refused to be killed, he couldn't die, he feared it. He would do anything to find the Orange Spider Lily so he could walk underneath the moon light again.

Until then, he would stay hidden from the demon slayers. Try to make his own chemical that had the same reaction without the Orange Spider Lily.
