Although Kenzaburou Tondabayashi is a 52-year-old bureaucrat, he is well versed in reincarnation stories where a protagonist suddenly awakens in a fantasy world. After being hit by a truck, Kenzaburou lands in that exact situation. However, what baffles him is the fact he wound up in the world of an otome game—as the young villainess and the daughter of a duke, Grace Auvergne. Fortunately for Kenzaburou, he is somewhat familiar with his new world, as it is based on the game called Magical Academy: Love & Beast. He was a proud father in his previous life, and he often listened to his daughter rave about the game's setting and characters. Armed with background knowledge and a lifetime's worth of dad skills, Kenzaburou strives to make the most of his new life, though his kind-hearted nature makes it difficult to fully embrace the role of a villainess.

Edo-period Japan stands strong and proud, decades after its imminent doom was prophesied. The new shogun, Yoshimune Nobu Tokugawa, encounters an array of traditions that, to her modern judgment, make little sense. An epidemic exclusively rages among men, resulting in men making up only one-fifth of the population. Still, three thousand young, agile, and beautiful men serve in the Oooku—the shogun's Inner Chambers. To unearth the origins of the existing hierarchy where women head their families and govern the nation, Nobu reviews the chronicles of the odd disease. Customs and traditions have changed to accommodate for the plague; these new laws dictate the current culture and reflect the cruel story of the first female shogun, Iemitsu Tokugawa. Most notably, these customs seem to lead back to the moment a young monk, Arikoto Madenokoji, must abandon his way of life and devote his remaining days to the shogun and her Oooku.
