Kaijin Kaihatsu-bu no Kuroitsu-san

Synopsis

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. Over the course of development, the Cannon Thunderbird designed by committee is scaled back until it is released as a large talking bird with a simple visor and headband. The monster is easily defeated by Blader in its first battle, as Blader wonders why Agastia didn't make the monster into a giant mech with tons of weapons.
