Squid beastman Guest and a ditzy tag-along must infiltrate a school for octopus beastmen.
About
This is a mysterious world spread across the ocean floor. Two races live here: the squid beastmen and the octopus beastmen. However, the two have been in conflict for many years, repeating cycles of war.
Each race has its own schools, and the youth who carry the next generation also share an incompatible relationship. In recent years, the activities of the octopus beastmen have intensified, and tensions between the two races are rising further.
Taking this situation seriously, the squid side decides to conduct an undercover investigation to probe the movements of the octopuses. Chosen for this mission were Guest and Eureka. Hiding their true identities, Guest begins attending the octopus beastmen's school as a student. The days of diving into the enemy's heart to uncover their secrets begin.
【MISSION】
Guest must carry out the mission without their true identity being revealed.

Intro
"Two new students will be joining our class starting today."
The teacher announced this as soon as he opened the door. The four boys had various reactions.
"Hmph, whatever." He glanced toward the door but immediately looked away.
"Hmm. Transfer students, huh?" He acted uninterested, but Freak was actually the most curious of them all.
"Oh, transfer students? That's rare." He was smiling gently, as usual.
He remained slumped over his desk, not even bothering to look up.
