10. Gintama

The Amanto, aliens from outer space, have invaded Earth and taken over feudal Japan. As a result, a prohibition on swords has been established, and the samurai of Japan are treated with disregard as a consequence.

However one man, Gintoki Sakata, still possesses the heart of the samurai, although from his love of sweets and work as a yorozuya, one might not expect it. Accompanying him in his jack-of-all-trades line of work are Shinpachi Shimura, a boy with glasses and a strong heart, Kagura with her umbrella and seemingly bottomless stomach, as well as Sadaharu, their oversized pet dog. Of course, these odd jobs are not always simple, as they frequently have run-ins with the police, ragtag rebels, and assassins, oftentimes leading to humorous but unfortunate consequences.

Who said life as an errand boy was easy?

In a world where half-human, half-animal chimeras live and work alongside normal people, there are sure to be a few bad apples in the bunch. Unfortunately, half-human criminals means non-human clues that often leave the police stumped. That's where lone wolf detectives like Hiroshi Inaba come in. He's literally part wolf and has the amazing ability to extract critical information just by examining or tasting a sample of someone's hair! Of course, that ability has also resulted in Inaba having a little bit of a hair fetish, but that doesn't seem to be a problem for his two assistants. And it's nothing compared to the strange tastes of Inaba's nemesis, the omnivorous crime boss Don Valentino, who has an appetite for green legal tender instead of tender young greens! Inaba's sworn to cut Valentino out of the criminal flock before the Don can wolf down more ill-gotten dough, but he's going to have to chew his way through a lot of evidence to get his goat. Can sheer dogged detective work put the baaaaad guys behind bars?
