Similar to Tekkon Kinkreet, Satoshi Kon's Paprika uses a more realistic style when it comes to the designs of the characters. These more realistic characters are placed in stylish and often times psychedelic settings. The dream world in Paprika gives off a similar vibe to Tekkon Kinkreet's fictional city, Takaramachi. The two movies don't share any similarities when it comes to the overall plot, but they both are set up in a similar fashion, featuring stories that allow the art to really stand out by focusing more on eccentric and unusual ideas.

Kakurenbo follows the story of a group of children who gather to play a game of Otokoyo. Otokoyo is a game of hide-and-seek that can only be played by seven children wearing fox masks. It is no ordinary game, however, as the children are chased by demons and always end up missing. A young boy named Hikora joins the game in hopes of finding out the truth behind the game and to find his sister Sorincha, who went missing after she played the game herself.

With Kakurenbo only being the length of an average episode of anime, it doesn't have time to develop its characters and narratives like Tekkon Kinkreet does, however, the world Kakurenbo builds is just as enjoyable. Kakurenbo is different from every other movie on this list in the way it connects to Tekkon Kinkreet. None of the stories or characters are similar, but it still manages to give off a similar vibe to Tekkon Kinkreet. With more of a focus on horror, Kakurenbo's setting is very dark adding to the suspense and making great use of its setting. By using its setting and art style, it is able to create an immersive world similar to how Tekkon Kinkreet uses its art style to create an impressive world.

Akira shares many of its story elements with Tekkon Kinkreet. Both movies feature a pair of orphans that live in a city with a corrupt government. Black and Kaneda are also very similar, with both of them being gang leaders and taking care of a younger boy that looks up to them. Both shows also start out with the main characters a fight with a rival gang, and these fights go on to set the rest of the story in motion. Both sets of main characters get split up and both Akira and Tekkon Kinreet spend a large majority of their time focusing on the boy's adventures to try to reunite and restore things to how they were before.

Perfect Blue is a much darker and gritty movie than Tekkon Kinkreet is, however, the two movies still share some common themes. Both Perfect Blue and Tekkon Kinkreet feature many elements from the psychological genre and toss in some action and suspense. Mima's degrading mental state is similar to what we see Black go through in Tekkon Kinkreet. Mima and Black both go through events early on in the movie that ends up causing them to lose control and start to see the world differently. Although the settings in Perfect Blue and Tekkon Kinkreet are very different, the way in which they are used is very similar. Both movies add to the overall tone of their stories by incorporating their settings perfectly, with Perfect Blue using its darker tones and more realistic setting and Tekkon Kinkreet focusing on a more colorful world with much more action going on in the backgrounds of each scene.

Loups=Garous may not be as colorful as Tekkon Kinkreet, but both movies have many similarities when it comes to their story and characters. Both movies follow the story of kids fighting against the corrupt worlds they find themselves in and end up getting wrapped up in a mystery that is bigger than they ever thought possible. Both movies antagonists are the corrupt governments that the main characters find themselves living under. Hazuki Makino and Ayumi Kono from Loups=Garous also have some of Black's more enjoyable character traits. Hazuki shares the traits from Black's more caring and protective side, as she goes out of here way to protect her friends, ultimately resulting in her getting wrapped up in the murder mystery and putting her life in jeopardy. Ayumi Kono, on the other hand, shares the traits from Black's more rebellious side, with her going against the status quo of the world around her, and she uses her power to fight against it.

Together with a group of deformed inmates with special abilities, Retro and Pandy must fight against the corrupt prison guards, and break out of Dead Leaves.

Dead Leaves is another movie that has more similarites to Tekkon Kinkreet by way of its aesthetics more than it's plot. While not using the more realistic character designs, Dead Leaves has artistic and creative settings. The worlds in both movies are colorful and combine aspects of real architecture and a large number of fantasy elements, which gives the viewer the ability to experience unique and enjoyable settings. Although Dead Leaves has a heavy focus on its comedy, it also has many action scenes that impact the story, similar to how Tekkon Kinkreet uses its actions scenes.
