Astarotte's Toy

In the magical realm, succubi survive and sustain their power through a “life seed” taken from men, a necessity that also ensures the continuation of the royal bloodline. Princess Astarotte “Lotte” Ygvar is expected to keep a harem close for that very reason—an obligation made complicated by the fact that she can’t stand men. With Lotte’s future at stake as she nears maturity, her attendant Judith Snorrevik travels to the human world in search of someone the young princess might be able to accept.

Judith returns with Naoya Touhara, a 23-year-old single father brought to Lotte’s court as her first attendant. Naoya settles into the unfamiliar world by focusing on caring for Lotte and earning her trust rather than approaching her with desire. But when his daughter, Asuha, is later allowed to join him, the fragile balance between Naoya and Lotte begins to strain—pushing him to work even harder to mend what’s been damaged.

As Naoya grows closer to Lotte, it becomes increasingly apparent that his arrival wasn’t simply a matter of convenience. Threads of fate start to surface, linking Naoya and those around him in ways that suggest a deeper purpose behind his place in Lotte’s world.
