Summary

European royalty come to Japan to indulge in BDSM with a not-so-average high school student. A Christmas-themed romance story between a Japanese high school student and a refined yet wicked European noblewoman, Klaudia, who transfers to his high school and exploits his masochistic-ish superpowers, which allow her to perform divinations for the benefit of her kingdom. Also contains an alternate route featuring her SP escort, Julia, who is already skilled in torture for practical purposes but grows to truly love it when inflicting pain on the protagonist.
