On a remote island governed by its own anarchist rules, AC Company manufactures combat androids designed to look like young women. These mechanical maids arrive for final training before deployment into the world, and Rinia is the newest addition to the program. Problem is, she's lost all her memories and has no idea what she's supposed to be doing. Her well-intentioned efforts to be useful around the mansion create chaos at every turn. Takahiro runs the training facility, but he's a mess of a person: depressed, withdrawn, and convinced that Rinia will only make his life worse. He's also missing his own past, nursing wounds he can't quite remember receiving. As days pass, something shifts. Rinia's genuine attempts to help, no matter how catastrophically they fail, start to wear down his walls. What begins as mutual frustration slowly becomes something neither of them expected: actual connection. This three-episode OVA balances comedy with genuine moments of tenderness, asking what it means to build a relationship with someone when you're both running on empty.
