The first volume of a Gigantic Formula manga by Oka Shouhei has just been released (it's possible been running in Dengeki Daioh without me realizing it since I don't get that magazine)

Took me a while to find, as it is under "kishin taisen giganteitsuku fuo miyura" (the DVDs use "kijin taisen"). Eventually nailed it by misspelling the author as "oka shiyouhei".
