Kotone Aizuhara, a university student and dedicated fudanshi, met his end during a bookstore visit when a truck crashed into a book stand, leaving him buried under fallen yaoi volumes. He awoke in an alternate world where no women exist, finding himself within an ancient Asian-inspired palace. There, he encountered Nagi, a divine serpent being who declared Kotone his destined bride, or Miko. Nagi explained their union was essential, requiring physical intimacy for his ascension to dragonhood. Drawing on his deep familiarity with boys' love tropes, Kotone instantly recognized his expected role in this dynamic. He resolved to carefully leverage his knowledge of story conventions to navigate the situation, specifically aiming to avoid romantic entanglement and maintain personal boundaries within his predetermined position. His experiences adapting to this world and its expectations form the core of his journey across all animated adaptations.
