Gehstapoko is a blonde, curvy character who lacks male genitalia and embodies a sadomasochistic aesthetic. She serves as a Punishment Counselor at the Spartan Institute, a position earned through her past performance at the Auschwitz Academy. Her primary role involves confronting the protagonist Kekko Kamen. To lure Kekko into conflict, Gehstapoko straps Mayumi Takahashi to a giant swastika and throws knives to remove Takahashi's clothing, forcing Kekko's intervention. Their subsequent fight highlights a thematic element: individuals with sadomasochistic inclinations intrinsically desire physical punishment like whipping. During the battle, Kekko Kamen uses nunchucks to strip Gehstapoko of her leather outfit, exposing her physique, and ultimately defeats her with a headshot that renders her unconscious.

In one sequence, Gehstapoko lands on the head of Garisuke Igaya, a student intensely focused on studying and oblivious to the fight. This incident underscores her physical presence, chaotic combat style, and connection to other characters' narratives.

Conceptually, Gehstapoko's design and role draw inspiration from Blue, a hermaphrodite character in Go Nagai's *Violence Jack* series. Her visual design incorporates distinct eye elements reminiscent of Naojiro Abashiri, further situating her within Nagai's creative universe.
