"Chuunibyou" or "eighth-grade syndrome" is a condition where people believe they have super powers. The first time I heard this term is in the anime Chuunibyou Demo Koi ga Shitai! Is this syndrome real? Is there any medical term or at least more common term for this?

Togashi Yuuta from _Chuunibyou Demo Koi ga Shitai!_: "...this boy was a textbook example of eighth-grader syndrome too."

    I think users at Cognitive Sciences would know the name of this disorder, but I doubt many of them have seen the anime to understand what's being asked of them.

Chuunibyou describes teenagers around the age of fourteen that try to look cool to impress people around their age and are self-important trying to be unique.

This way of thinking, however, may continue even after the teen reaches adulthood, but it does not actually relate to any medical condition or mental disorder.

It's more like a growth phase for some teenagers.

Based on "Chuunibyou User Manual" (中二病取扱説明書, Chuunibyou Toriatsukai Setsumei Sho) by Saegami HYOUYA, there are 3 types of chuunibyou.

  1. DQN-type pretends to be antisocial even though they aren't, or can't be and has made-up stories about antisocial behavior (gang fights/crime).

  2. Subculture-type/Hipster prefers subculture or minor trends just to be different and have the "cool" factor. (obsessed with imitating idols/fictional characters)

  3. Evil Eye-Type admires mystical powers and pretends to have one of their own, to the extent of establishing an alias just for that.1

An example of DQN Chuunibyou:

"Look at all those bandages wrapped around you! What happened?"

"I had a bunch of gang fights."

"Come on, I know you're too kind to be a gangster."

An example of Subculture Chuunibyou:

"When I collect Pokémon cards, I only collect ones that are imported from Japan."

"Can you read all those?"

"-_-; S-sure I can..."

An example of Evil Eye Chuunibyou:

"Don't take that bandana off my left wrist. It's sealing an evil spirit inside me and if you take it off I may go berserk."

"Dude, calm down. You just have chuunibyou."2

    Please note that the severity as depicted is usually not as extreme (although our protagonists could just be outliers). Commented Apr 14, 2014 at 13:19
  • @ShinobuOshino The particular set of characteristics described by the term "chuunibyou" is very uniquely Japanese, and as such, there aren't any alternative terms that accurately refer to the idea of "chuunibyou". That said, if you'd like to consult the forum thread linked as reference 3 in the post, you'll find some close, useful descriptions in English of chuunibyou-like behavior. Doing dumb things isn't the exclusive province of Japanese teenagers, after all.

As for medical term or more common term for chuunibyou, they actually show it on first episode.

enter image description here

eight grader syndrome, pubescent crisis, fourteen sick, hebephrenic schizophrenia, 8th grader syndrome. A decade ago it was still considered to be part of the rebellious age of puberty.

I couldn't find any reliable source of pubescent crisis or fourteen sick but there are a lot explanation about hebephrenic schizophrenia and it seems like hebephrenic schizophrenia is more chronic mental disorders then the chuunibyou we know

From wikipedia (emphasis mine):

Disorganized schizophrenia, also known as hebephrenia or hebephrenic schizophrenia, is thought to be an extreme expression of the disorganization syndrome that has been hypothesized to be one aspect of a three-factor model of symptoms in schizophrenia, the other factors being reality distortion (involving delusions and hallucinations) and psychomotor poverty (lack of speech, lack of spontaneous movement and various aspects of blunting of emotion).


Yes, it’s a real thing.

In reality, Chuunibyou is way more common than we usually think. That’s because it isn’t just about pretending to have superpowers, but rather about pretending in general. And its categorized into 3 types by how people tend to pretend.

Hope I answered your question. If you’re still curious, try:

    Hey, Sorry to disappoint you but I'm not affiliated with it. It's just a site that covers niche topics in great detail and as you said I have their information easily available. If I know a better source of information, Then I will link to it and If it's not necessary, I won't post any links. It might seem like I'm spamming links, but in reality, It just because I haven't been a member for long enough. Commented Nov 15, 2018 at 21:16
