Ami is left alone to protect Earth after her partner departs the planet. However, her troubles take a surprisingly serious turn due to the sudden appearance of a mysterious woman during an undercover investigation. This woman keeps changing forms—appearing as a photographer when Ami is a swimsuit model, as a ghost when she's a shrine maiden, as a female teacher when she's a schoolgirl, as a female coach when she's in gym clothes, and as a female doctor when she's a nurse. She is a constant torment to Ami. Amid this, Mugi, a female student Ami grew close to during her investigation, goes missing while looking into rumors of a vampire. Ami investigates disguised as a nun, but is captured, crucified, and drained of her blood. Though she briefly escapes to a space carrier, the mysterious woman appears again as female high priestess Paula, captures Ami, and interrogates her. As Ami continues fleeing, Paula takes Mugi hostage to lure her out. Helpless before Mugi, Ami is tortured and humiliated. Ultimately, this leads to a BAD END.
