Project Libitina is a cryptic, high-stakes human experimentation program conducted by the mysterious Religious Organization at the Vierhofen Medical Center. Originally hinted at through hidden files in Doki Doki Literature Club, the project involves testing "Third Eye" abilities on humans, resulting in lethal symptoms or extreme behavioral changes like self-harm and vocal cord paralysis. In the Dimensional Coalescence and Doki Doki Takeover lore, the project is often linked to the true origins of the club members—specifically Yuri, she is somehow able to posses and take control of her at times, causing more insane, bloodlusting, and obsessive behavior.
