After enduring countless years of ascetic training to inherit his parent's shrine, our protagonist is surrounded by a parade of cuties with a surprise! Despairing over not being able to enjoy a "normal" love, he seeks the aid of his local enshrined deity. And as if the heavens themselves heard his plight, the Goddess manifests in front of him. But fate would deem that the Goddess he unsealed was... a trap Goddess! "Come, let us be united in marriage!" "I want a normal girl, thank you very much!" The shrine will become the stage where the legend of trap conception will be born!

Our protagonist thought he could return to his daily routine after the rivalry between his two new wives ended... But alas, it was not to be, since the sudden appearance of the newly appointed crossdressing goddess, Tamaki, shook things up. While our protagonists were gone in another dimension, Subaru—who was exiled by Mishiro once upon a time—returned, and made Tamaki the main goddess of the shrine, assuming direct control over the shrine's authority. As her first order, Tamaki banned all romantic displays of affection between men and crossdressers, which ignite the ire of the newfound brides. What will become of their now forbidden love?! Will the hidden secret of Kotomusubi shrine be unveiled?! As men and gods recover their lost connections, a new crossdressing legend arises!
