About Quarta Alumina and Tangel

Quarta Alumina and Tangel is the third entry in Kudarizaka Guardrail’s battle ero and defeat RPG series, built with RPG Maker and presented as a 2D game with 2D CG art. You follow two powerful, justice-driven transforming heroines as they face traps, lewd attacks, and systems designed around their paired roles. As the battle ero and defeat RPG premise continues, the two heroines are worn down, defeated, and trained through pleasure until they struggle to resist even enemies they once ignored. The game is a Japanese title and explores fantasy, corruption, and humiliation.

The current build is v1.0.4, released May 4, 2026, with ongoing development. It runs on Windows and is available in English through translations by Gemini-2.5-flash and Gemini-3.1-flash. The game’s adult content is censored with mosaics.
