Tokidoki is a Japanese high school student who, when he fails his history class, is sent to a high-tech history museum that virtually recreates the Edo period to do make-up work. However, what was supposed to be a simple school project becomes much more complicated when he's attacked by two supernatural beings known as "the nue" and "the yakou" and loses the vision in his left eye. After he's saved from the nue by a girl named Kuchiha, he realizes that he's no longer wearing the simulation goggles, and is trapped in the virtual Edo. Meanwhile in the real world, Sensai Corporation, the virtual reality company who made the virtual museum Tokidoki is trapped in, is seen throughout the story.
An easygoing high school student who adapts easily to new surroundings. As a child, he was sent to boarding school by his parents, and they barely kept in touch with him. He was consequently taken care of by Suoh Kuwata, a law breaker type, and a young woman, Chitose; Suoh died afterwards, but he was a very important person to Tokidoki. Tokidoki's childhood friend is Momiji. He keeps in touch with a policeman involved with Sendai Corp., named Hashita.Tokidoki is not good at history, and as a result, goes on a field trip to a virtual reality Edo period. While in this world, he loses the vision in his left eye to the nue and yakou and finds himself trapped in this simulation of the Edo period. Called the "hakutaku," "hakushi no mono" (白紙の者, lit. "the one of blank page") by some in the virtual Edo, as his fate isn't foretold by Heaven's Net. The demons that want to protect the world want to make him the new "Teiten" or God of Amatsuki, since he is just as powerful as the current one. After being rescued by Kuchiha, for whom be worries in the beginning of the series (because she lets others hate and isolate her), he adapts quickly to his surroundings, but is living life as if it were a dream. He is under the care of Lord Shamon, a priest who cares after Kuchiha and someone he met from the real world just minutes before, Kon. Toki soon befriends more characters, including Heihachi, and he even goes on to attract the attention of the women in the town (he later befriends the demons that are hated by humans).After becoming acquainted with the virtual universe, he finds himself having to choose between siding with the demons, who will revere him as a god, or with the humans, including the Omnyouji Bureau, who want to get rid of the demons. He is stuck in the gray area, not wanting to choose one side, but both. He is warned about how dangerous this is, and has been asked to choose a definite side. In the recent chapters, we find out he has fallen in love with Kuchiha.

It is here that she is discovered by Kanzou, a boy with marked fangs over his teeth. Kuchiha lost the ability to speak, but Kanzou understood her and tended to her needs. One day, he set off to find a place where she would belong, and told her to wait where she was. However, she walked away from where she was supposed to wait, getting lost, and losing Kanzou, who was no longer able to find her. Years later, Kanzou finds her again, explaining that their destinies are bound together, for she is the dog god, and he is the destined servant of the dog god, Shirachigo( Gazu Hyakki Yakō ). Kuchiha, believing that Kanzou abandoned her, refuses to go along with him at first, but she concedes, leaving Toki with these words: "I'm not like you."
