Shingu aired from May 8, 2001 through December 4, 2001 on NHK. It ran for 26 episodes and was released on DVD on five volumes by The Right Stuf International in the United States.
In the year 2070, an alien invasion of Tokyo is repelled by a mysterious giant being which is almost a monster in itself. This battle is witnessed by Subaru Muryou and his grandfather who comment about it and watch it as if this is nothing to be surprised or shocked about, even though everyone else seems panicked. Later, a middle schooler named Murata Hajime witnesses Muryou and a student council member, Kyouichi Moriguchi, fighting each other with some sort of super psychic powers. This causes a series of events which brings Hajime to the stunning discovery that almost everyone in his school seems to know about the giant the news reported defeating the alien invasion over Tokyo. Further to his shock is that it seems everyone in the older part of the small town he moved to a few years ago holds this strange secret and in fact a deeper one, and has been holding it for many years.
The secret is that many of the leading families of the older part of the town have been using their powers and the power of the giant, called "Shingu", to protect Earth for centuries. As Hajime learns this, it comes as somewhat of a shock to him that all of the current members of the middle school student council are actually the guardians of this secret and of Shingu itself for this current generation. This includes Student Vice President Naiyuta Moriyama, who, as it turns out, guards one of the biggest parts of the secret of Shingu. While all of these discoveries are a huge enough shock to him, Hajime also discovers that many of the town's other residents are in fact intergalactic diplomats. The more he learns and the closer his friendship with Muryou, Naiyuta and the other members of the student council becomes, the deeper he is drawn into this open secret. Especially as his friendship with Naiyuta and Muryou grows deeper, Hajime slowly begins to realize he has a very large role to play in the future of both Shingu and Earth's protection.
