- Description from MTL

The world I transmigrated into was a dark fantasy game universe, devoid of hope or dreams.Doesn’t feel like it at all, though.

The male student, Fukai Nagamasa, ignores his studies for college entrance exams in favor of following the path to chuunibyou. As he fainted during night cramming session before the exams, he realized that he was transported to a parallel world as a feudal lord in the Sengoku Era. Not to mention that suddenly, he was marrying the sixth Demon King, Oda Nobunaga’s little sister, the one who was purported to be an unrivaled beauty?

After many years of unrequited love, she used her power and favors to coerce him into marrying her. Yet, she knew there was a constant “lunar light” in his heart. In the presence of this lunar light, he would never cast a glance upon her. Eventually, she regretted it, she no longer wanted this marriage. But who could tell her why the man had started to relentlessly pursue her now?
