It has been serialized online via Flex Comix's Comic Meteor website since April 2019 and has been collected in five tankōbon volumes.

Plot

Throughout Japan, there are both evil secret organizations that seek to conquer the world, and superheroes who rise up to challenge them. One such evil organization, Agastia, operates out of a base hidden underneath a front company headquartered somewhere in Tokyo. Agastia's attempts to conquer the world are often thwarted by the superhero Divine Swordsman Blader. This story focuses on Miss Kuroitsu, an assistant in Agastia's Monster Development Department, responsible for creating a monster powerful enough to defeat Blader once and for all. However, this organization operates like any large corporation, as Kuroitsu and her Department are forced to fight for resources and funding with other Departments in the organization, make proposals to the board to justify their costs, or deal with their leader's whims forcing them to redo their designs at the last minute.

Megistus, the Chief of Staff of the evil secret society known as Agastia, explains how the group's competition is struggling against superheroes of their own. The Monster Development Department comes up with a new monster that looks like an old man wearing a Nessie-like mascot outfit, holding a sword. Kuroitsu is angry at her superior, Doctor Sadamaki, for forcing her to present an underdeveloped proposal to Agastia's board after throwing the idea together at the last minute. Even though Akashic likes the monster, Megistus soon rejects the proposal. Lacking the time and funds to design another one so soon, Kuroitsu is forced to wear the Nessie costume herself in an ill-fated battle. Later, after buying some takeout from Kenji's restaurant, Kuroitsu and Sadamaki are putting the finishing touches on Wolf Bete, a ferocious wolfman who has been training in a virtual environment until his body can be finished. On the day his body is ready, Wolf Bete discovers his body was changed to that of a wolf-girl, at Akashic's last-minute request for a "cute" monster, but his mind is still that of a wolf-man, giving him gender dysphoria. Later that night, Wolf Bete attacks the superhero Divine Swordsman Blader, shown to be Kenji's secret identity, in hopes of earning a big enough reward to get his expected wolf-man body, but ends up in a draw when Kenji's inexperience with women and Wolf Bete's embarrassment at being stripped naked stop them both from fighting.

After Sadamaki comes down with food poisoning, Kuroitsu is forced to take his place on a business trip to Kyushu to observe how a similar evil organization deals with fighting against superheroes. During the trip, Kuroitsu stays close to Megistus, marveling at how he can compartmentalize his brain to efficiently perform work for the company, test the many products developed by Agastia's affiliates, and get rest simultaneously. Even at night, Megistus shows consideration by giving Kuroitsu his hotel room and working overnight at a nearby hostel. Back at Agastia's HQ, Bete is officially transferred into the Monster Development Department as their newest assistant, though he still hates the cute wolfgirl body they gave him. Sadamaki reveals the department's latest proposed monster, the Cannon Thunderbird, a large mecha-like bird monster with railguns and thunder-strike abilities. However, because of the large amount of mechanical parts involved, the team is forced to collaborate with other departments within Agastia, plus their leader Akashic's whims.

As Kuroitsu stumbles into Kenji's restaurant, she accidentally inspires him to remember why he became Blader in the first place. Next week, she redesigns the Hydra to have four extra heads.
