As the human race evolves, so does its technology. Engineers have successfully created robots dubbed Labors for mass distribution, utilized by society for a number of everyday tasks. However, there are criminals who manage to get their hands on these Labors, using them for their own nefarious means. To combat this new form of delinquency, police around the world begin using Patrol Labors or Patlabors to put a stop to Labor-related crimes. Rookie police officer Noa Izumi is drafted into a special Patlabor unit, getting her own mechanical suit to fight crime. Naming this machine Alphonse, Izumi works tirelessly alongside her peers to keep civilization safe from those who would use this advanced technology to harm others. As Izumi becomes further ingrained within her unit, she must also learn how to navigate both her social and professional spheres with grace and wit. She befriends the aloof Asuma Shinohara, fellow pilot Isao Oota, and the other members of her brigade as she helps them to combat conspiratorial plots, workplace revolts, and supernatural beings.

They are entitled 'Everything you always wanted to know about Nereids (but were afraid to ask)' and 'Heaven can wait for Maia Mizuki'. These stories are more lighthearted and comedic in tone, bordering on silly.

Some offices have stereotypical dynamics: the chauvinistic pig of a boss who never does any real work; the employees whose goal is to suck up to the boss; the ones whose lives seem perfect; and the individuals who have all the actual work pushed onto them.

Her relief from the stress of her everyday life comes in the form of singing death metal at a local karaoke club. Night after night, Retsuko channels her grief into a microphone and considers the place to be her own personal sanctuary. But as she moves further away from her comfort zone and the ideas people have of her, she discovers that letting others into her world of death metal may not be such a bad thing.
