The Dengeki Game Festival 2012 event — streamed live via NicoNico Douga — has just released word of a new 「Ichigeki Sacchuu!! Hoihoi-san」 anime project in the works. The exact format — TV, OVA, etc — has yet to be disclosed.
The time is the near future. Cockroaches and other household pests have become immune to all forms of insecticides. In response to this crisis, a Japanese company has created small, doll-like, insect exterminating robots called Hoi Hoi-san. A competing company has also released their own version, Combat-san. Because of their adorable appearance, these little robots have become somewhat of a phenomenon and have gained many fans. Late at night, in the home of one such fan, Hoi Hoi-san and Combat-san search for insects to exterminate… but Combat-san is not above trying to exterminate Hoi Hoi-san while shes at it.
