Karakuri Circus

Both anime are based on older 90s action shonen manga series written by the same author. Also both of them are being animated by studio VOLN and share similar comedy elements 

the story of both anime revolve around a Kid who try to escape from an evil corporation he run into the MC then he recruit the MC to protect him from the evil corporation ,a lady joined and help the Mc to protect the kid , later the kid and the MC find out some secret that link them with this evil corporation. this two anime focus on action, mystries and suspense the MCs of both shows have the same personality . the kids have the same personality . even the art style is the same . Overall Karakuri Circus is the closest anime to No guns life and they both worth watching. read more 

The monster characters are very similar, in both series the main villain manages and creates other monsters, and the newly involved male character helps the woman after learning the information from the woman who knows the events. 

Both shows share large parts of their staff. Same Character designs and the overall vibe and atmosphere is extremely similar to Hunter x Hunter (2011) 

I don't know how to describe it, but they both have the same feel to them. Karakuri Circus is about a boy who's travelling around, running away from an organisation after his money that was handed down to him from his father. Fullmetal Alchemist is about two boys travelling around the country, trying to find a way to get their bodies back. 

Both have puppets and puppet masters whom were at war with each other, where one side fights to survive, while in the other anime the ones were fighting were out to save souls of people.  

Both are absurd and play with the tone. Either incredibly serious or don't take it seriously. Also aren't afraid of letting characters die, or redeeming villains 

Grand-scale stories with a large sum of characters whose potential is brought down by ridiculously fast pacing. While not entirely comparing the puppets from Karakuri Circus to the Shaman's partners, Guardian Ghosts serve the purpose of helping the characters in their fights, puppets in KC are more of a tool unlike ghosts' distinct personalities in Shaman King. They also have interesting fights complimented by their environment but I'd argue Shaman's visuals look more janky while the work by Studio VOLN on KC is the highlight of the whole show. (I'm willing to do an update once I finish Shaman King, whenever that may be, in the meantime I suggest you'd check out Karakuri Circus, despite the grueling pacing the story gets a satisfactory ending and it's overall fun even if it becomes very dumb and needlessly complicated) read more 

Adding on to jRad522's "Supernatural summons with their ridiculously dressed owners" I'd argue Karakuri Circus is also a story that talks about lineage or generations like Jojo. In a way, the tireless battle against Dio is similar to the Jin and Yin brothers-debacle of Karakuri Circus, a villain that lives through the body of others and counts with a horde of obedient underlings for our heroes to fight. Just like how ridiculous Jojo battles can get with stands, the fights between puppets and Automata can get as creative as the previously mentioned show, with one having to do with a guy carrying an entire merry-go-round machine on top of his head. Over-the-top action, extravagant/overconfident villain's claims, fights that take place in a train and airplane, like in Jojo part 5, but still, I'd say it's similar to the introduction of stands itself, Jojo part 3, with the main puppet, Harlequin, bearing similitude to the cool nature of Star Platinum and being the most overpowered summon of the show. read more 

well, both of them skips a lot of plot explanations and are sometimes cliched as hell but still you just can't bring yourself to hate them,lol  

Both shows feature marionette puppets and have dark undertones, backstories, and themes to them. There is some dark comedy laced in both shows as well. 

In a way, Karakuri Circus is a shounen, anachronic version of Ghost in the Shell. Artificial humans - androids/puppets and theme that examined whether this artificial version of life can understand how humans feel, why they act and whether this can be replicated by machines. Also included cyborgs - humans with part of their body exchanged for mechanical parts. While in Ghost in the Shell this is all done with science, Karakury Circus doesn't really try to present a "realistic"" technology and it's a puppetry, machinery and alchemy. 

Both these series have a dark aesthetic to their art style. They both have themes about strings, puppets and non-human beings and their struggle to make regular choices like humans. They both also have likeable character and great OST's. 

Automata are very similar to Homunculus in that they're non-human artificial beings. In that sense I guess Shirogane's are similar to Alchemists too. Both are also shonen with super powered battles. Both have great art styles and character designs.

While not anything alike in plot, both shows feature mystical puppetry as their main gimmick. They both have highly stylized characters, both feature suspense, mystery, and violence, and both will likely not get the attention they deserve. They're also both an interesting mix of silly and violent, which is a fun combination.  

They have a similar vibe and both are adventure shonen. They also both have quite a story hidden behind their battles between silly yet creepy carnival-like foes. Will humanity survive or have their last laugh? 

Supernatural summons and their ridiculously dressed owners have violent, campy battles with mysterious stakes.
