Pure x Holic Junketsu Otome to Konin Kankei

Daichi becomes the husband candidate for three demi-human queens bound by the Laplace Seize, a rigid racial contract that strips them of their free will in love. To liberate them, Daichi uses a mystical tool called the Diagnosis of Refusal, engaging in intimate acts with the queens to sever their predestined causality. By breaking these chains, he allows them to experience genuine affection and choose their own destiny.
