Stop trying to understand what's happening. The whole joke is that nobody involved knows either, including the characters who are supposedly making a manga about it. You're watching three girls improvise their way through the most genuinely unhinged slice-of-life comedy ever committed to disc, where the punchline isn't the gag itself but the fact that they're all completely committed to nonsense as if it were documentary realism. This is what happens when a comedy special decides it doesn't need plot, stakes, or even coherence to be funnier than shows that have all three.
Ai-Mai-Mi: Mousou Catastrophe Shojo Kuriya is a 2014 comedy special in a slice-of-life vein. The single episode was never broadcast and was instead included with the Blu-ray and DVD release, which makes it a bonus piece for viewers who picked up the home video edition. Its full romaji title ties it to Choboraunyopomi Gekijou Dai Ni Maku.
