A mysterious lifeform organization known as Deathkatze is executing a secret plot to dominate humanity. Leading this sinister group is the villain Hell Angler, who devises a plan to eliminate each member of Bird Five one by one, starting with Bird White, Mio Fukayama. He isolates her by drawing her comrades into combat, leaving her completely alone. Hell Angler attacks using fishing-based weapons and eerie, worm-like creatures resembling bait, tormenting her with relentless and varied assaults. He pierces Bird White’s chest and groin with fishing hooks, yanking and snapping the lines, whipping her mercilessly with a fishing rod until her body is covered in wounds, and dousing her with a special seawater solution—subjecting her to countless forms of excruciating torture. Yet, Bird White refuses to surrender any information. Next, an electric eel designed for torture closes in on her most intimate area. Can Bird White endure this relentless barrage of painful and pleasurable torment?
