Ysflare is held captive by Void-sama, who has corrupted her partner Ysaqua into a lust-driven weapon to break Ysflare's will. Through extreme psychological and sexual manipulation, both warriors are stripped of their dignity and brainwashed into abandoning their pursuit of justice. Now transformed into the "Evilphere," the former heroes are publicly humiliated and enslaved, serving as pawns in Void-sama's sinister plan to ascend to godhood.
