William Thomas Jefferson III, an American Shorthair cat, is a failure at being a model like his famous father. Escaping his father's abuse, "Jeff III" tries to make his own way in the world, but finds it difficult to keep a job (being a cat creates issues). He is saved from the brink of suicide by humble ramen chef. Believing he has found his true calling, "Jeff III" opens his own ramen shop, adopting the moniker "Taisho" (Master). Business -- and his ramen -- isn't particularly good, but he manages to eke out a living, and even finds a love interest. However, when a rival ramen shop opens on the same block, Taisho faces the biggest challenge of his life -- especially when he learns who the "Shogun" is that runs it. Based on the comic strip by Kenji Sonishi.
