It is Spike, a lot of the staff were from Human Entertainment. Except for Fire Pro Wrestling and dragon ball games, they are more known nowadays as a publisher for niece titles in japan, they actually published the dragon age games, Haze, Dead island and other stuff, big titles in the west, but small in japan.
But they also published japanese titles like 999: Nine Hours, Nine Persons, Nine Doors(chunsoft), Michigan(grasshopper manufacture), 428 (PS3/PSP versions only), Madworld (platinumgames), and other titles.
As Human Entertainment they were know for some cult stuff like Clock Tower, Twilight Syndrome and a lot of other classics, most of those IPs are owned now by spike.
BTW suda goichi used to be employed at Human Entertainment as well, until the company went busted. Spike, Grasshopper manufacture and Nude maker were kind of offsprings of it.
