Amatsuki - S01

Tokidoki Rikugou is a student who hates history and fails his Japanese History course. His high school makes him retake it by attending a special museum lecture. The main attraction there is a huge recreation of the Edo Period that promises to help the failing student improve his grade with a detailed simulation of the Tokugawa Shogunate: the Edo Bakumatsu Walking Tour and Exhibition. He knows almost nothing about samurai culture or the era he has stepped into, and he is soon surprised to learn how superstitious Japan was in the 1600s. He quickly dismisses the existence of gods and demons, so he is shocked when a demon confronts him on a bridge and attacks him. A mysterious swordsman named Kuchiha saves him, and he finds that he can no longer escape the simulation at the history museum. He meets another swordsman named Kon Shinonome and discovers another person from his own time who was trapped in the simulation before him. Adjusting quickly to his new life, Tokidoki must now help protect the village from demons while uncovering the mystery of both the simulation and the company that created it.
