During the live streaming of the Dengeki Game Festival 2012 (ゲームの電撃感謝祭 2012) on Nico Nico Douga, it was announced that a new “Ichigeki Sacchuu!! Hoihoi-san (一撃殺虫!!ホイホイさん)” anime project is currently in the works. However it is still unknown whether this would be a full series or another OVA (similar to the one that was released back in 2004).
Hoihoi-san 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.
Hoihoi-san is the bug killing robot of the title, a 10.5 cm tall doll like robot that comes with a wide range of weapons. With this character a new level has been attained in the girls-with-guns genre: capable of an impressive rate of fire, handles a sword equally well, is dressed up very cutely, complete with bowties and booties and an expressionless face. The Hoihoi-san series of products parodies the girls with guns genre, robot girls as companions and the otaku.
