Rui was a very small Demon child...the boy was whimpering in the bushes...he had cuts and bruises all over...the poor thing just wanted warmth and food...

Sanemi: did you hear that..?

Obanai: yeah I came from the bushes..

Mitsuri: Do you think it was an animal?

Tengen: ... Yeah I hear whimpering...

Giyu: ...Mh... Maybe a demon...

Rui was whimpering uncontrollably
