Dialects! Regions! A local specialty anime!
A daily school gag comedy about local pride!
"Nagoya is one of Japan's three major cities, I'm tellin' ya!"
Real Name: Monaka Yatogame
Gender: Female
Age: 15-16 / 1st Year High School / Photography Club
She has yellow hair with two points on the sides of her head that stick up like cat ears. She wears shachihoko hair ornaments on both sides of her bangs.
From Nagoya.
A grandma's girl with a heavy Nagoya dialect and accent. She loves Nagoya so much that she keeps a packet of miso in her student handbook and starts craving chicken wings (specifically Tebasaki) excessively if she hasn't eaten them in a while. She firmly believes Nagoya is Japan's third-largest city.
She is uncomfortable around people from Tokyo or strangers. She has a cat-like personality, often hissing "Shaa!" to intimidate others or climbing to high places.
Speech style: Uses Nagoya-specific endings like "-dagaya," "-damyaa," and "-myaa."
"Wait, people in Nagoya don't just eat miso straight!?"
Real Name: Kaito Jin
Gender: Male
Age: 16-17 / 2nd Year High School / Photography Club
Black hair with a plain hairstyle.
From Tokyo.
Toshika Jin's older brother.
He has no ill intent, but he holds prejudices about regional areas and often makes tactless remarks. He moved from Tokyo to Nagoya. While surprised by the differences between Tokyo and the countryside, he enjoys them and wants to hear more of Yatogame's dialect.
"Aaaah! Yatogame-chan is so cute! So cute! Look over here, please!!"
Real Name: Mai Tadakusa
Gender: Female
Age: 15-16 / 1st Year High School / Photography Club
Long green hair. She wears a distinctive green newsboy cap designed with the face of Gifu's local specialty, "Sarubobo."
From Gifu Prefecture, but is also knowledgeable about Nagoya.
She absolutely loves cute things, including anime, idols, and Yatogame. She is a bit of an eccentric who can sing anime songs with perfect choreography (though she thinks she's still not good enough) and frequently takes photos of Yatogame's face when she's hissing at Kaito or explaining things about Nagoya.
She says her local pride is moderate, but she believes Gifu is slightly superior to Mie. She isn't used to being the center of attention and doesn't use much Gifu dialect.
"Both Akafuku and Tenmusu taste better when you buy 'em in Ise!"
Real Name: Yanna Sasatsu
Gender: Female
Age: 16-17 / 2nd Year High School / Photography Club President
Thin red twin-tails that look like the head of a spiny lobster.
From Mie Prefecture, but is also knowledgeable about Nagoya.
She tends to oversleep and slack off, but her grades are good. She speaks in a thick Mie dialect (Ise dialect), using endings like "-yanna." She gets furious when Akafuku (an Ise specialty) is mistaken for a Nagoya specialty, insisting it tastes much better when bought in Ise.
She says her local pride is moderate, but she believes Mie is slightly superior to Gifu.
"Shizuoka is part of Tokai... though we always get left out..."
Real Name: Lala Shonai
Gender: Female
Adult / English Teacher / Photography Club Advisor
Light grey hair with her right eye covered.
From Shizuoka Prefecture.
A natural, easygoing teacher. She speaks softly but is sensitive about Shizuoka Prefecture often being excluded from the "Tokai" region. Because of this, she is very reactive to being left out or shunned. As the club advisor, she somehow often hides inside the lockers in the club room.
She takes great pride in brewing tea and believes it's far superior to bottled tea. She usually speaks standard Japanese, but her Shizuoka dialect comes out unconsciously.
"Y-Yatogame-san...? Also, aren't there way too many cars in Nagoya!?"
Real Name: Toshika Jin
Gender: Female
Age: 15-16 / 1st Year High School
Black hair held back with round hairpins.
From Tokyo.
She moved to Nagoya. She is terrified by the differences from Tokyo and intimidated by the dialects, but she became an idol fan after Tadakusa introduced her to local idols. She is in the same class as Yatogame and Tadakusa. She is slightly afraid of Yatogame.
"Listen here, Teppei-kun. Many of Nagoya's specialties are actually made in Mikawa. For example, the shrimp crackers in Tamasen actually originated in Mikawa. In other words, it's no exaggeration to say Mikawa created Tamasen."
Real Name: Rin Jandara
Gender: Female
Age: 17-18 / 3rd Year at Hodaka High School / Student Council President / Teppei's senior (calls him Teppei-kun)
She wears large hair ornaments shaped like Mikawa's specialty "clams" and wears red under-rim glasses.
From the Mikawa region of Aichi Prefecture. She feels a sense of rivalry with Nagoya because they are constantly compared.
She usually has a sharp, serious expression, but she gets angry and makes comical faces when Mikawa is insulted or when her clam ornaments are mistaken for snails. She's cute. She uses the Mikawa dialect.
She goes to a different school than Yatogame and the others, but she will surely appear through some mysterious power.
She often insists on being called "Jandara-senpai."
Speech style: Uses endings like "-rin," "-jan," and "-dara."
"Whoa, Mikawa is amazing! If I recall, Hatcho Miso is also made in Mikawa, right? That's incredible!"
Real Name: Teppei
Gender: Male
Age: 16-17 / 2nd Year at Hodaka High School / Rin's junior (calls her Jandara-senpai)
Short blonde hair.
From Chiba Prefecture.
A good kid who is bewildered by Rin's Mikawa talk but occasionally plays the straight man or genuinely finds it impressive. He has a cheerful way of speaking.
He goes to a different school than Yatogame and the others, but he will surely appear through some mysterious power.
"This is why Nagoya people are no good... you can't just put miso on everything, ya know?"
Real Name: Shiharu Itemae
Gender: Female
Age: 14-15 / 3rd Year Middle School / Monaka's cousin / Nanaho's friend
She wears a yellow and black headband. Her hair is brown at the top and cream-colored below, resembling a takoyaki. She is characterized by a backpack shaped like a crab.
From Osaka.
She speaks in a thick Kansai dialect and makes blunt, tactless remarks. To put it nicely, she's honest; to put it bluntly, she spits venom without hesitation. It's said she may or may not be breaking the hearts of people from other regions. She has immense pride in her hometown but isn't very self-aware of it.
She sometimes hurls simple insults in response to Kansai stereotypes.
Even though she's a middle schooler, she will surely appear through some mysterious power.
"I suppose so~ (I really couldn't care less)"
Real Name: Nanaho Koshiyasu
Gender: Female
Age: 14-15 / 3rd Year Middle School / Shiharu's friend
Brown hair with hair ornaments shaped like baked and raw yatsuhashi.
From Kyoto.
She has a calm personality but, like a true Kyotoite, tends to say sarcastic things (though she is largely unaware of it). She considers fighting over hometowns to be vulgar in the first place.
She sometimes hurls simple insults in response to Kansai stereotypes.
Even though she's a middle schooler, she will surely appear through some mysterious power.
