Eat-your-heart-out romance!

Time has passed since The Demon Lord and The Hero have married and in the preceding years, both human and demon realms have been united. Mixing of demonic races and humans is not uncommon, but is encouraged to bring about a new age of prosperity and unity. Whether our story focuses on an ordinary student meeting a stunning and brilliant vampire girl, an exchange student training with beautiful knightley sisters, or a myriad of tales featuring succubi, dark elves, and fox deities, this world will never be the same!
