The Sushi Menace EP features Taku and Shiori who are the owners and head chefs of the House of Knives, a restaurant in which two previously-warring mafia factions have agreed to make a neutral spot for a very important dinner meeting. Both gangs have had an ongoing truce for the past year to stop fighting each other, and instead, turn their focus on the corrupt government. The outcome of this dinner could end in either a continued partnership between the mafia factions or a return to war.
Taku and Shiori are best friends who complement one another quite well. Both martial artists are masters with their blades and guns, with Shiori preferring smaller weapons, like knives and pistols, while Taku enjoys wielding larger ones, like katanas and rifles. Working at a sushi restaurant, they both are able to practice their martial arts while they slice, prepare, and serve delicious meals to their patrons by day. At night, they become the bounty hunters known as Sushi Menace. Regardless of the time of day, they’ll often be caught debating one another over various subjects.
