Original creator (manga) : Hideaki Yoshikawa
Plot summary : The "science trouble" romantic comedy follows Haruki Komaba a high school boy who has two eccentric girlfriends : Ayana Hizuki and Airi Kuze. The former is a purple-haired half-dog while the latter is a blonde-haired half-cyborg who go to extremes with the power of science. Haruki gets involved in perverted troubles caused by the two girls.
Note : The manga just launched in late 2010, and Akita Shoten published the second compiled volume last month.
It was announced to be a OVA bundled with the third manga volume.
Update : Cast announced : Ryota Ohsaka, Toa Yukimura, Ringo Aoba, Ryō Kasumi, Rino Kawashima (Kei Mizusawa), and Yuana Miyazawa. Given the risqué nature of the material, these names are not necessarily the cast members' actual names (except Ohsaka and Aoba).
