Miss KUROITSU from the Monster Development Department

Touka Kuroitsu, an assistant in evil secret society Agastia's monster development department, must do whatever she can to push a project proposal through.

Kuroitsu accompanies Megistus on a business trip to Kyushu, where she realizes Megistus's dedication to his job.

Kuroitsu creates a new monster, Hydra, to take out Blader. Unfortunately, budgetary concerns have caused most of the new monster's functionality to be omitted... and Blader appears to be in a big hurry!

Kuroitsu hopes to acquire pluripotent cells from Camula, Agastia's strictest executive. But it isn't until she attends an idol concert on a related matter that she finds her chance!

Kuroitsu's team needs a stamp of approval from each of Agastia's executives to get their latest request fulfilled. But terror (and frustration) awaits at each of their lairs!

Kuroitsu wants to create a special monster for Valentine's Day, but Akashic repudiates her lack of a proper feminine mindset. And so, the chocolate-making class begins!
