Sweat Punch

the characters, atmosphere and color palette are very simillar. 

Le Portrait de Petit Cossette and Comedy are dark and brooding anime that take the supernatural element to a whole new level of psychological ambivalence. Both are visually challenging and original in their take of emotionally upsetting horror.  

Both are anime shorts, which give you a glimpse of several different worlds. A variety and mix of everything. Both are worth a watch just to see the huge range of things animation can take us. 

Stylized gothic tale 

Both OVAs are anthologies of short stories made with various animation styles and techniques. 

Both are collection of short, some of them trippy anime done by Studio 4°C. While Sweat Punch is collection of stories, Fluximation is collection of music videos. 

(As Sweat Punch is collection of stories indipendent on themselves, this recommendation concerns only End of the World part) Both are short, a bit trippy anime with short episodes. Both have similar animation and very similar feeling, but End of the World may be a bit more darker. 

Both are collection of short, sometime a bit trippy stories, independent on each other, each with different animation and story made by different people. 

Note that this recommendation concerns only the short film called Kigeki (aka Comedy). Karas is longer but both anime share a lot of aspects. Both have a very dark atmosphere; a solitary dark hero, who is a man of few words; beautiful animation; awesome sword fights; and an amazing and orchestral soundtrack: Schubert’s Ave Maria in Comedy and Prague Symphony Orchestra in Karas. 

Visually distinct shorts with zero traditional exposition or storytelling, they convey most meaning through absurdism 

Forward thinking experiments in animation and visual storytelling made by auteurs in the anime medium 

Both are OVA that are collection of short, indipendent on themselves stories, each with different animation and story done by different people. Some can be a bit trippi and some stories from Digital Juice and Sweat Punch are made similary. 

* This recommendation is only in relation to an anthology episode of Sweat Punch, titled “Comedy”. They bear semblance in symbolic figure and contrasting relationship dynamic, in which a little girl embodies innocence and fragility; in need of company and urgent protection from an external threat, and a lonesome man who, in contrast, manifests a tinge of darkness and danger. The atmosphere is also fairly alike; staged in a calm and distant countryside overriden with dense forest, cozy cottage and warm fireplace— yet with the looming sense of imminent horrors. Both were made with a touch of European sensibilities and rather dark fairy-tale trappings. 

Similarly morose collections of whacked out stories. 

they both seem to have a dark, depressing yet meaningful feeling to them both. 

Though extremely different at first sight, these stories have the same feelings beyond the pictures. They are two monologues: a monologue of a cat and a monologue of a little girl, which describe to us their sense of life and their hopes. Somehow you would find equal atmospheres in Cat's love story and Comedy's childhood story. 

At first glance, this recommendation may seem a tad off but Princess Tutu and Comedy are some of the few titles that incorporate classical music with the animation proper in a way that is both relevant and artistically done. In both there is a great importance given to story telling and to narration techniques. While Princess Tutu is not as forlorn as the very dark Comedy both have an aura of dreamy surrealism that is highly captivating.  

While at first glance these shorts seems to be on opposite ends of the spectrum - Kigeki a fictional story set in the historic Irish War of Independence, Diary of TR set in a surrealist world with no ties to reality - there exists a very similar feeling between them: The style and colors are luminously muted, both stories leave the viewer with no real sense of closure, and both create a strong attachment to the characters with very little (or no) dialogue. 

They both have the same dark theme. The art is dark, as so is the story. And plus, Kigeki has to do with The Black Swordsman liking a certain type of book, while in Death Note, there's a book that can kill other people. 

(As Sweat Punch is collection of stories indipendent on themselves, this recommendation concerns only Garakuta no Machi part) In both, a young boy encounters robot that decides to hang around him. Both anime have robot that gets bigger by eating metal scrap and other metal stuff. FLCL is more dementia.  

"Rain Town" and "Garakuta no Machi" (5th story from "Sweat Punch" series) are both short and slow paced animes. They have different atmosphere but the plot have similar themes. We see alone child exploring near future world in both of this animes. The child meets an artificial intelligence and communicates with it. "Rain Town" is voiceless and "Garakuta no Machi" have only a few conversations. However, "Garakuta no Machi" is more optimistic and have comedy scenes while "Rain Town" is sorrowful and depressive. 

A variety of short stories 

(As Sweat Punch is collection of stories indipendent on themselves, this recommendation concerns only Kigeki part) Both are action anime about a little girl that meets a mysterious vampire and becomes something like his employer. At the end, the vampire fighst whole army on his own.
