In this unusually light-hearted anime romp, our hormonal hero Aiwa is sent the wrong blowup doll by a mail order company and the doll, "South Pole #28" turns out to be extremely lifelike and moronically devoted to him. Aiwa, however, is infatuated with a flesh-and-blood woman named Kozue who really couldn't care less about him. The doll gets jealous of the real girl but rather than going Glenn Close on her owner, she exposes herself in public at every opportunity and lets him fuck her until his nose bleeds. At his unwitting instruction, she finds five guys to piss on her in a park and then she fights off them after they expect to fuck her after pissing on her. Maybe every blowup doll has limits. Who knew? The story ends with Aiwa choosing the doll over pursuing real women after being inspired by the depths of her programmed love for him, a romantic finish that will make viewers want to hug their inflatable lovers just a little tighter.
