The OVA format lets this thing commit fully to the bit: a one-shot parody that knows exactly how absurd it is and never apologizes for the premise. Kocho's sexiness is treated as a literal combat tool that stops working the moment a female spirit shows up, and the show finds genuine comedy in that constraint rather than retreating to fanservice. The chemistry between Kocho, her sister, and their human decoy carries you through without pretending there's a story that matters, just three people having fun fighting spirits for 30 minutes.
Spirits have infested a local school, and nobody's equipped to stop them except Kocho Enoki, a student with both supernatural abilities and a body that works as a weapon in ways she's learned to exploit. Her strategy is straightforward: use charm and magic in tandem to neutralize the supernatural threats before they consume the entire campus. Alongside her sister and Kosaku, a reluctant human decoy, Kocho wages an unconventional war against the invading entities. The operation runs smoothly until a female spirit arrives, one completely immune to Kocho's usual tactics. This enemy forces the team to rethink everything, pushing past their reliable playbook into territory they haven't prepared for. What starts as a confident supernatural cleanup job becomes a genuine test of whether Kocho can adapt when her most effective tool no longer works. The tone balances action and humor with unabashed fanservice, never taking itself too seriously even when the stakes genuinely matter. This is high-energy, colorful entertainment built on the premise that supernatural combat can be both ridiculous and entertaining in equal measure.
