If you liked the Gintama anime, the Anime-Planet community thinks you'd like:
In a bizarre fantasy world, students known as meisters are trained at the illustrious Shinigami Weapon Meister University; but the tools they wield are no ordinary weapons! Each meister is paired with a human-like being who can transform into a weapon at will; and after defeating a pre-kishin - a human whose soul has darkened - the weapon eats the soul within it. A meister's ultimate goal is to collect ninety-nine pre-kishin souls and one of a witch so that his or her partner will become an all-powerful Death Scythe. Maka and her partner Soul Eater; Assassin Black Star and his partner Demon Blade Tsubaki; and Shinigami's son Death the Kid and his partners the Demon Twin Pistol Thompson Sisters each vie for their ultimate goal, but plenty of challenges and adventures lie in their way!
Both shows are very amusing and worthwhile. A huge cast of interesting & memorable characters, action and lots of humor makes these series very similar to each other. So if you liked the action/comedy ratio of one series, you will surely enjoy the other as much. Be sure to check it out!
Space Dandy is a space hunter, someone who is paid to search for new, undiscovered alien species. It's an industry where the prize goes to the person who finds aliens the fastest. Dandy searches unknown planets for strange beings with his companions, QT the worn-out robot and Meow from Betelgeuse. Meanwhile, they're being chased by minions of the Gogol Empire, for reasons that are still a mystery.
The eccentric mad scientist Okabe, his childhood friend Mayuri, and the otaku hacker Daru have banded together to form the Future Gadget Research Laboratory, and spend their days in a ramshackle laboratory hanging out and occasionally attempting to invent incredible futuristic gadgets. However, their claymore is a hydrator and their hair dryer flips breakers, and the only invention that’s even remotely interesting is their Phone Microwave, which transforms bananas into oozing green gel. But when an experiment goes awry the gang discovers that the Phone Microwave can also send text messages to the past. And what's more, the words they send can affect the flow of time and have unforeseen, far-reaching consequences - consequences that Okabe may not be able to handle...
Both of these shows are gag style comedies that mock the traditonal samurai values. They both love to use puns and wordplay to create a lot of their humor. Most people think of more serious themes when they think of feudal Japan so both these shows are kind of surprising in the light hearted approach they take to the topic. If the puns and word play in Gintama amuse you them you should definately check out Tono to Isso.
“Vash, the Stampede” - worth 60 billion dollars to the one who can turn him in. Bounty hunters everywhere are on the lookout for this legendary gunman, not to mention insurance agents Meryl Stryfe and Milly Thompson, who are tasked with preventing any potential damage that this Vash can cause. But with 60 billion on his head, Vash is not an easy man to find.
Trigun and Gintama are rather different kinds of anime. Whilst Gintama focuses on the humor aspect, Trigun is more mixed between humor drama and action. But the main reason I recommend watching Trigun if you liked gintama is beacuse the main characters are rather alike, in my oppinion. Both are lazy and goofy on the outside while they have a fierce tiger and a romantic personality inside.
