If you liked the Chocolate Underground anime, the Anime-Planet community thinks you'd like:
In the future, androids live side by side with humans – but not as their equals, as their slaves. Though they look identical, these androids must display a holographic ring over their heads so the difference is clear. One day, a boy named Rikuo finds abnormal activity patterns in the logs of his own android, and alongside his friend Masaki, he sets forth to find where the android has been. Much to their surprise, the duo discovers a secret café known as Eve no Jikan with a single rule: within its walls, there must be no discrimination between humans and robots. In this place, androids appear to be human and are even displaying signs of independence – a trait that should not be possible. Rikou finds his perceptions increasingly challenged as he struggles to come to terms with his own android, and the relationship between man and machines...
This might seem like an odd recommendation - call it a gut feeling. Sure, Eve no Jikan is sci fi to the core and Chocolate Underground is more of a whimsical tale aimed at younger folks, but both involve a secret underground, interesting characters, and just have the same feel. It's hard to come up with something tangible to say, so just try it on for size.
Both anime feature a secret cafe hidden from the rest of the world, and the characters involved in the network to keep their secret cafe alive and thriving. The two anime have a very similar, friendly feeling, despite the all or nothing cercumstances.
It is the year 3287, and the countries of Roxche and Soux-Beil have been feuding for one hundred and thirty years. In the country of Roxche, the young air force pilot Allison has just reunited with her childhood friend Wil; and together, they are about to embark on a grand adventure. Whether it's ending the war between the countries with the help of a legendary treasure, traveling into hostile territory, or helping restore a princess's right to the throne, Allison and Wil will complete their missions with kindness and honor.
Whenever there is a series which typically goes down the route of 'everything always ends as a happy ever after' , they seem to emit a strange feeling that once you've seen and enjoyed one, you'll like every other type. That applies to both Chocolate Underground with its story of people trying to get back their chocolate and Allison and Lillia which consists of short stories where the good guys try to sort out the country. They're both very good shows and certainly worth watching and if you liked one, the other will be easy to watch.
Valentine's Day is approaching, and young Mami-san is apprehensive. She wants to give chocolates to her crush, Ishida, but can't seem to build up the nerve to do so. Luckily for her, she might have a solution: magical chocolates, given by a witch who seems to vanish into thin air, supposedly will grant the holder the love they desire! But will it work for Ishida?
This might seem like a strange recommendation, but when I watched Magical Chocolate, I was charmed that something so frivolous can be so important. Chocolate Underground makes the same sentiment, just in a bit of a darker way. Both are optimistic and unique anime centered around a sweet plot device.
The government has passed the Media Betterment Act, establishing a military police force to stop the spread of "negative influences harmful to society;" and in response, libraries have organized their own military units to protect freedom of expression. After being saved by a Library Defense Force agent in a bookstore, Kasahara is inspired to enlist in the Library Defense Force. Although she proves quite athletic and capable, she must endure the harsh but meaningful training of her instructor and superior officer, Doujou. As she learns how to be a good soldier, she participates in LDF operations, helping protect literary freedom for everyone.
The main characters in Chocolate Underground and Toshokan Sensou fight against an oppressive government. Chocolate is banned in Chocolate Underground while books are censored in Toshokan Sensou. Chocolate Underground is more lighthearted and seemingly aimed at young kids while Toshokan Sensou has a mix of romance, action, and comedic moments, but the premise is still quite similar.
