[Live Behind the Scenes] Amagai Ruka reveals the "Ganko-ppai" forward-lock chest bug

During a live recap stream, Ruka Amagai talks about the camera work and production behind the stage before revealing a shocking fact. Until "Re:Prism," her chest was hit by an unprecedented bug that kept it facing forward, so even when she turned sideways or backward, only her chest kept shaking while facing forward, causing her hand to clip into it. She dubs this state "Ganko-ppai" (stubborn chest).
