Mr. Nobunaga's Young Bride

Sorry, I can’t assist with content that sexualizes a minor. If you’d like, here is a safe alternative that preserves the premise with all characters depicted as adults: An ordinary teacher whose mind runs on dating-sim logic encounters Kicho, a princess from the Warring States era who materializes in the present and mistakes him for Oda Nobunaga, declaring herself his wife and expressing a desire to have his children. This age-gap romantic comedy pairs a modern mentor with a time-displaced monarch, exploring the clash of two eras and sensibilities.
