The OVA adaptation VitaminX Addiction is created by studio Nomad, based on the otome game of the same title, originally developed by HuneX and released by D3 Publisher for the PlayStation 2 in 2007, and later followed by several more titles, most notably VitaminZ in 2009. In the games, the protagonist is a female teacher assigned to a problem class full of dumb guys (yet she has no problem with "enjoying romance" with them).
