House Jigen (ハウスジゲン, Hausujigen, 6): Originally a hotel mansion infused with Radiguet's Dimensional Bug on its forehead, this monster managed to devour many people before the Jetmen meddled in its feeding affairs, forcing House Jigen to reveal itself and attack the city. It also served as the battleground in the first fight between Radiguet & Red Hawk. This was the first monster destroyed by the Jet Icarus.
