将軍様はお年頃

Nobuyuki is a normal student who was involved in a traffic accident. After regaining his consciousness, he found himself in the Edo period!

Yoshimune, a beautiful swordswoman whose hobby is vanquishing evil.
Muneharu, the flashy daughter of one of the three great families.
Tamaki, his imouto who also time-slipped to the Edo period.
Rin, a shy kunoichi who lives next door to him.

Along with these four beautiful girls, he acquired possession of the cheat sword “Reitou Retsuzan”, which has a mind of its own, to become the greatest swordsman of Edo. It wouldn’t be long before the battle for the mysterious ‘hidden treasure’ would lead to a major event that would shake the Shogunate.
