Demon Knight Ingrid · Oath of Humiliation Episode 3 / 4
After capturing the ninja Murasaki and the Dark Knight Ingrid, Kiryuu subjects them to biological modifications that grant him total control over their bodies and drastically heighten their sexual sensitivity. To avoid betraying her master, Edwin Black, Ingrid agrees to a degrading pact to service one hundred men in exchange for the right to die. Both women are subsequently forced into a public brothel, where they are humiliated as slaves for Kiryuu's demonic clientele.
