Trope Namers and Codifiers
- Hikaru Ijuin is said to be the first person to use this word as it was heard in his radio programme Hikaru Ijuin's UP'S. During an episode which aired on 11 November 1999, Ijuin mentioned, "I'm still contracting 'chuunibyou' myself". In the following week, Ijuin started a corner called "Am I sick? Oh, it's just Chuunibyou." in which Ijuin reads "cases" contributed by his radio listeners in his radio. Ijuin originally described chuunibyou as the things people normally do during their 2nd year in middle school. As the term grew more popular, it became a slang term among Japanese internet users. Other derogatory terms such as "High School 2nd year Syndrome" (kounibyou), "Elementary School 2nd year Syndrome" (shounibyou), and other similar derivatives started appearing and also became Internet memes. It was then that Ijuin himself tweeted a message regarding this issue by saying, "I have no interest in this word anymore because it has lost its original meaning from when I first described it."
- Chuunibyou User Manual by Saegami Hyouya is basically an All There in the Manual for this kind of syndrome, becoming even a reference for future works in Japanese Media. The book was released on 2008 under Kotobukiya publishing and even having its own manga based on this book.

Anime and Manga
- Masayoshi Hazama is one of the main characters of Samurai Flamenco. A male model by occupation, Masayoshi has a love for Super Sentai/Power Rangers-type shows, and has always desired to be a hero of justice. One day, he decides to get a custom sentai suit made to finally live out his dreams as a hero. While he has no fighting experience, he gives his all when acting as a superhero, trying to instill the concepts of truth and justice into the delinquents he runs into while on patrol. He believes himself able to convince these kids of the path of justice, and able to hold his own in battle, although neither of these are particularly true. Still, he never gives up on his dreams and believes that with enough dedication he can truly become a hero like the ones on TV.
- Yu-Gi-Oh!: Before the manga became entirely about card games, one Villain of the Week was a classmate who claimed he could see the future (and arranged for his predictions to come true). When exposed by Yugi, it turned out his predictions were all prewritten, such as "There will be an earthquake". In Japan.
- Daily Lives of High School Boys
- Shaman King
- Wooden Sword Ryu and his gang are the Japanese Delinquents Who Don't Do Anything, who act scary but never break any rules and can be so considerate at times that it verges on comical.
- In the Sequel manga Shaman King: Flowers, Hana accuses Yohane of only acting like The Rival because of chuunibyou. He's correct.
- In Pani Poni Dash!, Behoimi acts like a Magical Girl, though she grows out of it over the course of the series.
- In Martian Successor Nadesico, Jiro Yamada (or as he calls himself, "Gai Daigoji")note is a Hot-Blooded Real Robot pilot who thinks he's in a Super Robot series, shouting out the names of attacks from his favorite anime while in combat. He also serves as something of an inspiration to the rest of the cast especially when he dies during battle, even those who claim to find his behaviour annoying.
- Love Live! Sunshine!!: Yoshiko Tsushima, or, as she prefers to be called, Yohane. She believes she is a Fallen Angel who has been cursed and banished from the heavens (but it turns out she just has extremely bad luck).

- The Disastrous Life of Saiki K.: Shun Kaidou is a Conspiracy Theorist who has a secret identity known as Jet-Black Wing, fighting to protect the world from the Dark Reunion. In actuality, it's implied that Kaidou is Obfuscating Stupidity and only keeps up the antics as an outlet because he comes from an extremely strict household with an Education Mama.
- Kanzaki Ranko from the THE iDOLM@STER: Cinderella Girls mobile game anime adaptation is an example of this.

However, despite being chuunibyou, she is innocent and sweet and others find it surprising that she is really scared of horror and ghosts.
- In Boruto, Boruto starts acting like one when he thinks he's unlocked his Byakugan, complete with sunglasses and a smug attitude. Everyone else just finds his behavior weird and think he's making it up to get attention.

Another case is Hit Girl, which apart of becoming a vigilante and having real training and skills (with the same Evil Eye-type than Kick-Ass), she's also a Delinquent-type as well a Western example of a Tsundere.

She herself believes that she is a sorceress with the ability to see other people's destinies through her "Wicked Eye", which she keeps hidden behind a medical eyepatch. Hilarity ensues as the two begin to become friends and they start to learn more about each other's lives.
- Yoshiteru Zaimokuza from My Teen Romantic Comedy SNAFU has delusions about being a warlord in another life and even having a lifetime rivalry with Hachiman Hikigaya who also has a coincidence in his name just as Yoshiteru.

- Jurai Andou from When Supernatural Battles Became Commonplace is a shameless and textbook example of the Mystic type, to the point that Hatoko infamously chews him out for it. Also, depending on whether you believe they actually have powers or simply have overactive imaginations, every character in the series may also count.
- The 2001 mystery novel Hyouka (most known for their manga and anime adaptations) is about a group of students part of the Kamiyama High School's Classic Literature Club.

- Sanae Kochiya is an unusual example in that she really does have supernatural powers, she's just way too enthusiastic about them (and occasionally lapses into If Jesus, Then Aliens).
- Sumireko Usami is a textbook example of chuunibyou syndrome, being convinced of her inherent specialness, belief in mystical phenomena and general obsession with the occult, and superiority complex towards her peers and everyone else she meets prior to the serving of humble pie she gets at the hands of Reimu and Gensokyo's youkai. Unlike many other examples of this trope, however, she actually has very potent Psychic Powers.

He is a self-proclaimed mad scientist and villain, and will often partake in strange mannerisms such as talking to himself via cell phone and laughing maniacally in order to keep up this persona.

- Himiko Yumeno, the Ultimate Magician of New Dangan Ronpa V3 appears to be carrying on the trend. She wears a witch hat and insists her magic tricks are the product of actual magical powers.
