HoiHoi-san, full title Ichigeki Sacchu!! HoiHoi-san (一撃殺虫!!ホイホイさん, One-Shot Bug Killer!! Interceptor Doll HoiHoi-san^?), is a manga by Kunihiko Tanaka that spawned a PlayStation 2 game and a ten-minute OVA (sold with first printing of manga tankōbon). In the year 20XX, insects have become immune to all pesticides. To combat the rising plague of cockroaches and other household pests, the tiny, doll-like extermination gynoids known as "Hoihoi-san" were created. They can hunt down insects and kill them with such miniaturized weapons as minuscule machine guns and tiny combat knives. They can also (and at the same time) be treated as dolls, by dressing them up in costumes and buying accessories for them. The main robot of the anime wears a maid uniform and rabbit ears as accessories.

It started out as a manga title serialized in Japanese language monthly magazine Dengeki Daioh published by MediaWorks, and later branched out to PlayStation 2 as a game and then further into numerous other media channels. The setting is in year 20XX at a time when insects are immune to all insecticides, so Japanese pharmaceutical companies have had to come up with the next level in insect extermination: small but heavily armed robots.
