IKUSA: The 2nd War(2006)

Things have never been the same for the local Yakuza ever since Issa Mido invented the famous curry-squeezing device Shiboru-kun. Despite his invention being a big hit, he seems to have completely dropped off the map. The smaller families see Issa as an important tool in order to overthrow the head of the gang, and begin searching for him far and wide.
