High-school student Tokidoki failed his history exam, and to prepare for the re-sit, he has to join an excursion to an exhibition hall that uses VR goggles to recreate life in the Edo period. Tokidoki wanders off and gets attacked by a demon of some sort. At first he thinks it's a neat VR trick, but when he loses his glasses and the sight in his left eye, the demon is still there! During the attack, Tokidoki is transported to the past!
He finds himself in some sort of mythical Edo period, where magic, spirits and gods are very real. Tokidoki teams up with his classmate Kon, a hot-head who got transported during a demon attack as well -- he has lost all sensation in his right arm, but that does not stop him from getting in all sorts of fights. There is also Kuchiha, a girl who is a master swordfighter. She is possessed by a dog spirit, so everyone shuns her. This merry band of misfits gets involved in demon hunting, prompted by the priest of the temple where they're staying.
It turns out that three demons are trying to break free from the Net of Heaven, where everything has already been pre-ordained. And to do that, they need to manipulate someone to become the new head god of the world of Amatsuki -- but that can only be someone who has not been 'caught' in the Net. And sure enough: Tokidoki fits the bill! Because he was born in another world, his destiny wasn't foreseen, and so he is suited to become something outside of the system.
But of course, his demon hunting friends have a certain opinion about the nefarious plans of the demonic trio, and some high priestesses with magical powers get involved. Also, there's some youkai that have a grudge against humans who are more than happy to support the demons, so it all comes down to a large confrontation at the end!
If I had one word to describe this series, my choice would be 'bland'. The story, while full of potential, is so-so. The characters are all quite flat, and the main character is a total dweeb. Couple that to mediocre animation and second-grade voice acting, and you have something that's quite forgettable. The series is more than a year old, and still the list of episodes on Wikipedia hasn't been completed -- everyone seems to think it's a forgettable series.
As for good and bad points, there aren't many. There's nothing really toe-curling bad, but there are no moments where it shines either. Mediocre, bland and forgettable. I'll give it a 5.
