acai cOrner is a surreal horror RPG by moca-pz made in RPG Maker and released in 2020. It stars Mizuki, who, after falling into the sewers, turns into a magical girl and finds her favourite guitar. However, the sewers are filled with monsters, and she can die if she stays in the sewers for too long due to having increased difficulty to breathe. As such, she needs to escape as quickly as possible.

Tegron forgoes getting the guitar and, as such, avoids any fights with the enemies and gets the neutral ending in record time.
