The premise creates instant, high-stakes awkwardness. The classic trope of "fake relationship forced into real proximity" is dialed up to an absolute maximum. The character designs are sharp, and the voice acting does a great job selling both the action and the romance.
With episodes only being about 5 to 7 minutes long, there is almost zero time for world-building or an intricate crime plot. The investigation is really just a backdrop to get the two main characters into compromising, high-tension situations. Final Thoughts: secret mission sennyuu sousakan wa zettai ni

She checked the imprint on her wrist — three bruises from yesterday’s training, a map of the route under translucent skin. The dossier called it Location C; she called it a schedule to beat. Objective: retrieve the ledger, leave no trace. Time window: twenty minutes between the north guard's cigarette and the service elevator’s hourly maintenance pause. She moved like someone who had practiced refusal until it became a reflex — not brave, not reckless; absolute.
She slid the heel pads into place and folded the micro-torch into her sleeve. On paper, there were contingencies for every lock and a photograph of the corridor in noon light; in practice, she would follow the rhythm of footsteps. Tip: memorize three distinctive sounds in any room — a clock tick, a humming vent, the scrape of a chair leg — and use them to keep count.
To understand the phenomenon, we must break down the title’s core components. Sennyuu Sousakan refers to an undercover investigator or infiltration operative. Unlike traditional detectives who work from the outside, these agents are thrown into the belly of the beast. The phrase Zettai ni (absolutely / by no means) functions as a narrative sword of Damocles. It implies a binding rule, an unbreakable vow, or a tragic flaw that the protagonist absolutely must not violate.
The series follows Kuroki Haru, a elite operative working for a clandestine government agency known only as "Division Zero." Her mission: infiltrate a sprawling, fortress-like private academy known as Gesshoku Gakuen (Eclipse Academy), which is rumored to be a front for international data laundering and the recruitment of child prodigies into a shadow syndicate.
The line between operative and target blurs completely. Kagetora reveals he knows Haru is a spy but chooses not to report her because he sees her as a potential escape route. The agency, sensing Haru’s wavering loyalty, sends a cleaner—a ruthless assassin posing as a gym teacher—to eliminate both Haru and Kagetora. The finale of the first major arc sees Haru holding a gun to her handler’s head, screaming, "I will absolutely not let you hurt them!"—a direct inversion of her original orders.
