Meet Sosumi Brown. In her regular identity, she's known as the strict, tough-as-nails principal of the Ikenobo School - but to the gangsters and seedy underworld elements in Japan, she's known as the paddling Punisher! When Tokyo's number one crime family summons up a demonic Oni to bolster their power, it's up to Sosumi and sister Hashi (along with Sosumi's trusty steed Kiso) to stop their hellish rampage!
