Wife Stealing: Ikumi and Shizuka

On the surface, physical education teacher and former swimming champion Ikumi Sunohara appears energetic, well-liked, and living a pretty normal life. But her close friend Shizuka starts noticing something is off. Ikumi's behavior has shifted in ways that are hard to pin down, and Shizuka, unable to let it go, starts digging. That decision pulls her directly into the orbit of Tanba Gouzou, a deeply unsettling individual, and things get genuinely dark from there. This single-episode OVA, adapted from a visual novel by Teatro Nishi Tokyo Studio, is less about shock value and more about the psychological tension between two women whose friendship gets tested in brutal ways. The story leans into themes of trust and betrayal, and the character dynamics between Ikumi and Shizuka give it more emotional grounding than you might expect from the premise. If you've watched something like Netorare: Tanabe Yuuka no Dokuhaku and appreciated when the genre slows down to develop its characters before pushing into darker territory, this has a similar rhythm. Fans of Shinyuu Netori: Netorareta Onna will also find familiar emotional beats here. It is explicitly adult content, so go in with that understanding, but if you're looking for a hentai OVA that at least tries to build atmosphere and give its characters some weight before everything unravels, Tsuma Netori delivers that in a compact, single-episode format.
