Toushindai My Lover: Minami tai Mecha-Minami

Without warning or explanation — no return address, no note, nothing — a life-size nude doll that a guy never ordered shows up at his door. He names her Minami. Then his actual little sister, also named Minami, walks through the front door and immediately clocks the situation. The look on her face probably says everything you need to know about the tone of this thing. This one-episode OVA from 2001 leans into the awkward domestic comedy of that setup before going full hentai. It's a weird little premise — part 'mysterious delivery gone wrong,' part sibling tension, part erotic fantasy — and it doesn't pretend to be anything other than what it is. If you've seen Chobits and thought 'what if they just skipped the emotional subplot entirely,' this scratches a similar itch, minus the world-building. The doll-as-companion concept also echoes things like My Little Lover, though the execution here is much more straightforward. The comedy comes from the sheer absurdity of the brother trying to play it cool while his sister is visibly losing her mind over a doll wearing her name. It's not deep. It's not trying to be. The appeal is entirely in that specific flavor of 'this situation is ridiculous and everyone involved knows it.' Short runtime means it doesn't overstay its welcome. Go in knowing what genre you're watching and you'll get exactly what's on the label.
