Midnight occult civil servants

Young Arata is ready for his first day on the job at the Shinjuku ward office. But when he gets there, he finds that it involves talking to supernatural entities!

Arata has been gifted with "Sand Ears", an ability that allows him to understand the speech of the supernatural Anothers. With this power he sets out on a new investigation: to solve a series of complex thefts involving magical items.

Arata is now trapped in an abandoned hospital beneath the ground, while hordes of zombies are flooding Shinjuku park.

It's time for the Nocturnal Community Relations division to do its yearly check-up of several of the Anothers in Kabukicho. Most of them are fine, but one has awoken after a long slumber, and has big plans.

People are disappearing and losing their memories in two elevators in City Hall. Arata and his co-workers go to investigate, but Arata finds himself trapped in another world.

Sakaki becomes convinced that he knows where his missing sister was taken. But his determination will find her will lead him to abuse his trust with the rest of the department.

The department descends into hell itself to get back Sakaki's sister and Miyako's friend. But when they get to their destination, they find there's nothing they can do.

It's a non-workday, and Miyako is ready for some R&R. But Kohaku has other ideas, and drags him across the entire city.

The Shinjuku Ward Office meets Satoru Kanoichi, from City Hall, whose attitudes towards the Anothers seem more clinical than what Arata is used to.

Arata and the agents from City Hall head to Olympic Stadium to investigate a possibly dangerous nest of Anothers, where he faces a difficult situation.

The situation at the Olympic Stadium escalates into an all-out crisis. The Shinkjuku Ward Office is granted the authority to set things right with the Silkworm Princess.

A lost, amnesiac Another is taken into the Shinjuku Ward Office. Arata struggles to find a suitable home for the Another.
