Rikka Takanashi is a teenage girl who possesses the strongest ocular power known to man: the Tyrant’s Eye. She's currently locked in a fierce war with a shadowy organization, and the fate of the world may hang in the balance with each passing battle... or at least this is what she believes. In actuality, Rikka is merely a normal high school girl afflicted with chuunibyou syndrome, a "disease" that makes one prone to delusional flights of fancy. Meanwhile former chuunibyou sufferer Yuuta Togashi is enrolled at the same school, looking to put his embarrassing junior high exploits behind him. However, when Rikka discovers his past life as the "Dark Flame Master", she uses this to her advantage to include him in all of her wacky schemes! With Rikka’s zany behavior dragging him further and further from normalcy, Yuuta must try to pull her back into the real world – or risk getting sucked into hers!
The plots of these shows are completely different. Chuuibyou features teenagers whereas Samurai has adult characters. However, both shows are delusional people trying to function in modern society. They often do embarassing things and get into trouble because of these delusions. Also, both shows feature a straight man character that tries to help out the delusional character. Both shows are light hearted and include a lot of comedy.
Chuuibyou has better animation and has some fantasy action scenes that take place in the character's head. Samurai is more dialogue heavy and doesn't have the action scenes, but if you like humorous anime about character with delusions then you should try either of these anime.
If you are enjoying the superhero antics of Masayoshi Hazama, you should check out Chuunibyou Demo Koi ga Shitai! And if you are enjoying Takanashi's insistence of resistance to the Dark Forces, you should check out Hazama's superhero Samurai Flamenco. Both anime feature characters who are out to save/improve the world using extra-ordinary methods. In Chuunibyou, Rikka Takanashi is trying to save the world from the dark forces which only a special privileged few know exist.
Both Taka and Hazama are zealous (over-zealous even!) in their beliefs, and do not care what the rest of the world thinks of their method of choice in defeating evil. Taka uses custom-rigged everyday items endowed with supernatural forces to fight, while Hazama dresses up in his superhero costume to improve society and punish and admonish rule-breakers.
Both have a more-or-less "straight" man buddy to accompany them and ground them to reality, when their tendency is to take flight into their own private universes. Taka's friend is a school buddy and neighbor Yuuta Togashi and Hazama has a cop friend, Hidenoro Goto, who knows his secret identity.
If you enjoy buddy anime, and want to see age old fight of good versus evil played out with a new batch of heroes, check out either of these similarly themed shows.
In Sternbuild City, corporate logos not only cover billboards, but also the costumes of the super-powered heroes that act as its protectors. Veteran and newcomer warriors of justice alike compete in a reality TV show that offers points for apprehending criminals while giving champions' sponsors a chance to promote their brand. When the low-ranking Wild Tiger loses his backing after a string of outrageous, botched rescues, he finds himself paired with an up-and-coming spotlight-seeker called Barnaby. But with their wildly different personalities, will the pair be able to save their beloved Sternbuild City and win the game show, or will their constant tension be the undoing of the world's first hero team?
Both series have a more down-to-earth take on superheroes (or masked heroes in Samurai Flamenco) and how they would function in modern society. Both have a male lead duo that exchanges a lot of banter back and forth, and neither is especially serious.
If you found one to be in good fun you might want to check the other one out.
Both of these are shows about super heroes in a real world setting. They both feaute a pair of male leads that have interesting dialogues between them. Also both shows take a more light hearted approach to the material with lots of humor.
If you like one then you should check out the other.
Both shows give me the same bubbly sense of the world being basically a good place and the main characters have a lot in common. Both Hazama and Takuto are good people seeking to make the world a better place, often to the skepticism of more "practical" individuals. There may be no mechs in Samura Flamenco, but the tone is very similar and the show is very quirky.
If you like one main character I think you'll like them both, and they both carry their respective show very well amid a full cast of other interesting individuals.
