About Mafia Certificate

Mafia Certificate is a Ren'Py dating sim by Gremory, built with animated 3D CG art. You play a male college student forced to relocate to the 9th City and attend a prestigious private university. Several mafia gangs control the city, and your character has ties to them, so your goal is to hide that connection while navigating romance, harem, and netorare themes.

The current build is v0.6.1, released August 10, 2026, and development is ongoing. It runs on Windows, Linux, Mac, and Android, is available in English and Thai, and is uncensored. The latest update adds Ninghua's main story and one side quest, Rain's story, a new story flowchart system, a Dating App that is still being improved, Chinese language support, a new cover for $20 supporters, and an updated Helena model.
