淫紋闘技都市ソドム ～大観衆の前で強制受胎させられる聖戦姫～

In a barren desert region untouched by royal rule for centuries, there exists a city that has maintained its autonomy — a place known as "Sodom", a haven of worldly desires and pleasures.

At the heart of this lawless city stands a massive colosseum where grotesque monsters fight against challengers in brutal matches. Losing doesn't mean death — it means being publicly violated in front of cheering crowds. Such acts are commonplace in Sodom.

To purify this city of depravity, two women are dispatched from the Holy Kingdom of Ernades. One is "Gloria", the "Iron Princess", a master swordswoman and the captain of the royal guard. The other is "Pamela", a "Holy Knight" who wields powerful divine magic. The two of them travel to Sodom as part of their royal succession trial — their mission: to convince Sodom's king to surrender and accept the Holy Kingdom's rule.
