Akira saves three years for the wrong computer, then gets handed something that wants to learn what it means to exist. The entire OVA runs on the tension between a guy who just wanted hardware and a biomechanical girl treating every human interaction like source code to crack. It's absurd and earnest in exactly the same breath, never choosing between the joke and the heart.
Akira has dreamed of owning the latest computer for years, finally scraping together enough cash to make the purchase. When he spots a rare model at a local shop, he rushes to buy it, only to discover it's already gone. Dejected on his way home, a mysterious stranger offers him a suspiciously cheap alternative. Without looking too closely at what he's bought, Akira takes the deal back to his apartment. What he finds waiting in that box isn't what he expected. Instead of cutting-edge hardware, he's now the proud owner of Mimi, a biomechanical girl from the future who emerged from the computer itself. She's advanced, curious about the past, and absolutely relentless in her attempts to understand human behavior. Akira finds himself juggling the chaos of hiding an AI girl from his landlord while figuring out how to send her back where she came from, assuming he even wants to. A chaotic comedy that cranks up the absurdity with every episode.
