GRET-23 Giant Heroine (R) Aries: Part 2

Renn, a medic member of the Earth Defense Force, rescues Nanako from the clutches of the Garan aliens, who are trying to steal Aries’s biological data. But after the Garan aliens infiltrate the base, Renn is captured and subjected to harsh treatment.

The Garan aliens disguise themselves as Renn, seize the opportunity, and take away Nanako’s freedom, tormenting her. They forcefully attack her again and again, while brainwashed male crew members join in, leaving Nanako with no choice but to endure repeated waves of overwhelming sensation.

In a desperate comeback, she breaks free and transforms to confront a monster, even with her body already battered. Renn, already conditioned by the aliens, stands before Aries as the final moment draws near…!? [BAD and HAPPY END]
