Kanashimi no Belladonna

An avant garde style animation themed around a main characters Deal with the Devil to attain power  

the art is very similar... 

Both have a similar art style and center around a mysterious and beautiful woman enslaved by her own desires. 

They are both great experimental, inspirational films with lots of artistic purposes. Tenshi no Tamago may take some visual inspiration from Belladonna of Sadness. 

This anime share some similarities with "Kanashimi no Belladonna," such as their exploration of taboo subjects, their experimental animation styles, and their willingness to challenge audiences with complex themes and ideas. They offer unique and thought-provoking viewing experiences that are sure to leave a lasting impression. 

Two stories of independece (or a lack thereof), with memorable visuals. Some scenes in Natsu e no Tobira greatly resemble the artsyle of Belladonna, with characters and backgrounds taking on the appearance of moving paintings. 

Both works are somewhat psychedelic and largely made up of gorgeously animated watercolor paintings 

These two anime are art house anime that have a artsy feel to them and have a really mysterious and unique character in the main role. These two anime focuses on supernatural beings and their affects on human beings.  

If you like one, you'll likely like the other. They give you a lot to think about. Both have themes of selling one's soul to the devil for revenge. Both feature female protagonists. Both center on themes of female trauma and a twisted sense of empowerment through accepting evil.  

Both semi-surreal and with a focus on women's issues - I guess? - (I don't think Belladonna is consistent enough to call it feminist) and sex 

Femme fatale female leads who use their sexuality as a weapon and psychedelic visuals. 

While not a perfect match in the slightest, Belladonna of Sadness does manage to strike a familiar chord of grandness that made The End of Evangelion such a unique and interesting film. 

Both are adult oriented stories about the mistreatment of women during the middle ages by the corrupt church. In Belladonna's case it's a pact with the devil, in Ikenie it's a succubus fantasy of a church related artist. In both cases there's rape of an innocent woman, who is then blamed of witchcraft and punished to cover up. Both have a hentai tag, but can be watched for the story alone. 

Ikuhara has attested to the influence of Belladonna of Sadness on Utena himself, and it absolutely shows. Both are feminist-positive, music-driven, artsy and psychedelic. Both also share a fondness for Art-Noveau that reflects in their art direction. Belladonna is more overtly psychedelic while Utena is more mature in it's treatment of it's themes (though admittedly is diluted by a few fluff episodes sprinkled throughout the series). Take your pick. 

They're actually not similar in terms of plot or theme, but they are both part of the Animerama trilogy, which consist of three rare adult-rated films. The Animerama films were produced by Mushi Productions during the late 60s and early 70s, which was founded by Osamu Tezuka himself.  

Surrealistic atmosphere and colorful art are common for Belladonna and Madoka, and both of them deal witches, therefore Madoka is much more positive TV-series. 

Midori and Kanashimi No Belladonna share eccentric but interesting artwork that essentially boils down into high amounts of nudity and disturbing content. Furthermore, both are incredibly trippy and make you question whether the explicit content exists for the purpose of commentary or not. I support the notion that they're style over substance but if you liked either you're likely to enjoy the other. These are also two QUITE memorable movies but whether that is meant in a good or bad way is up for you to decide. 

Both are centered around how women are viewed as mere objects of desire and how they are punished for just existing within the confines of the patriarchy. Imma Youjo takes a step further to show us just how rooted this shows up in folklore, science fiction, middles ages and the present. Equally as strong in it's feminist message but even more subverted since it uses it's pornographic content against the viewer to ask some profound questions.  

Beautiful, weird, psychedelic imagery, absurdity mixed with distorted depictions of reality, and experimental aesthetics of the '60s or '70s counterculture. Where the famous Belladonna of Sadness excels and exceeds our expectations, Yuukai Anna often falls somewhat short, while still being a mildly interesting work obviously inspired by the famous predecessor. 

Classic animation techniques complemented by thematically relevant music. Creepy and beautiful. Watch it to feel like the art school student majoring in animation that you've always wanted to feel like. 

Unconventional and unique animation style. Both are avant-garde and have psychodelic and trippy visuals ripe with symbolism and weird ideas. Mind Game is a coming of age story while Belladonna is a tragic tale. The director of Mind Game, Masaaki Yuasa, has been clearly influenced by Kanashimi no Belladonna and you can see this influence in a lot of his visual choices, animations and shot compositions in most of his works.  

Both are art animation, and focus on female as a sex object. 

both are extremely surreal, creepy and weird. both are strangely absurd. only in cat soup, they don't talk. 

There's similarities with the surreal, disturbing imagery and the unwelcoming medieval setting, particularly in the prologue and second half of Berserk (and even more with the manga's Conviction Arc). They both deal with the long-con/unavoidable deal with the devil. There are themes like the unfair distribution of power (from God or otherwise), and how a dramatic shift in that power would affect others, shared here. Griffith an Jeanne have similar transformations both thematically and physically. Also, Void kinda looks like the dick-devil. 

Belladonna of Sadnes has had a massive influence on the Shoujo genre, here apparent in similarities between it's ending and the ending of Sailor Moon's first season.
