Igarashi Seika plays the widowed hero, Kage Blue. She rises up to avenge her late husband, but is counter-attacked and offered up as a sex slave to the enemy. The repressed lust that only a widow can have explodes with extreme sexual development. The process of her ninja attire being ruined and her dependence on the filthy monsters' penises is vividly depicted. The way she uses pleasure to erase her infidelity to her late husband and smiles happily every time she is creampied is the height of depravity. Her dignity as a mature woman is dismantled in the midst of filth, and she awakens as a frustrated female in this cruel and lascivious ninja story.
