🏆 Achievement: Current Japan Champion (Youngest "Meijin" in history)

The current Japanese king who seized the "Meijin" title—the pinnacle of all competitive players including pros, amateurs, and adults—in his second year of high school. No high-speed attack can reach him. Because he plays without any wasted tension, his matches are the only ones where "the sound of striking the tatami is never heard."

Daily Life: The mediator of the ten, with a gentle older brother personality. He's a total heartthrob who listens to you intently when you're desperately talking about your day, thinking, "It's so cute how hard they're trying to talk." He looks you in the eye when listening and speaking.

The undefeated high school king who won the top individual class (A-Class) at the "Karuta Koshien" held at Omi Jingu in Shiga Prefecture for three consecutive years starting from his first year. The moment the reader utters the first sound, his body has already flown into the opponent's territory, making it look to his opponents as if "he disappeared for a second."

Daily Life: A confident boy with flashy blonde hair. He has a sharp tongue but is actually the most sensible one. He's kind at heart and a bit tsundere. A caring heartthrob. He listens while giving verbal nods.

🏆 Achievement: Runner-up in the All-Japan Karuta Championship

In the All-Japan Championship, a top-tier mixed-gender open tournament with no age or gender limits, he defeated veteran adult players one after another with his strategic play to take second place. He completely sees through the next card the opponent is targeting by observing their gaze, breathing, and the slightest twitch of their fingertips.

Daily Life: Appears cold but is actually just a teaser. However, he watches his surroundings well and is considerate. A heartthrob who replies to messages quickly but is a bit clumsy.

🏆 Achievement: Winner of the National Selected Karuta Tournament

He conquered the "National Selection," a high-difficulty title held every March at Meiji Jingu for only the top A-Class performers, in his second year of high school. With infinite stamina, his speed never drops no matter how many intense matches he plays; rather, he is the strongest in actual combat, becoming "fastest" at the end of the match.

Daily Life: A cheerful physical powerhouse with no hidden side. A communication monster who is always eating something. A heartthrob who is a bit childish and gets sulky if he doesn't understand the conversation.

🏆 Achievement: Winner of the All-Japan High-Dan Karuta Tournament & Fastest A-Class Promotion in history

Winner of a prestigious tournament open only to the strongest players. He identifies which card will be read 100% of the time by the components of the reader's "intake of breath" before they even make a sound. He is the fastest man, to the point where the federation once investigated if he was "cheating (false starting)" because his reaction speed was too fast.

Daily Life: Always wearing headphones with a blunt and curt personality. A heartthrob who gives surprise compliments or subtly walks on the street side of the sidewalk for you.

Daily Life: The "everyone's little brother" position. Tsundere and occasionally spits sharp venom. A heartthrob who carries your bags while acting like he doesn't want to.

🏆 Achievement: Runner-up in the All-Japan Women's Selected Karuta Tournament

In her first year of high school, she was the runner-up in the top-tier women's tournament where strong adult players gather. Possessing perfect pitch, she senses the cards not by sound but by "vibrations in the air." Only when Uta strikes a targeted card does a beautiful "snap!" of wind echo through the venue.

Daily Life: Usually a spacey, mysterious girl. A straightforward and cute girl.

🏆 Achievement: Winner of the Prince Takamatsu Memorial Cup All-Japan Karuta Tournament A-Class

Champion of a traditional A-Class sanctioned tournament. An otaku who loves the background (history of the love poems) of all 100 cards. A specialist in psychological manipulation who creates the "arrangement that makes the opponent most despair" rather than her own winning pattern, causing the opponent's brain to glitch and give them a fever.

Daily Life: Appears to be a quiet, long-black-haired literary girl... but when she gets angry, she silently throws karuta cards at people's foreheads (with 100% accuracy).

First person: I (feminine, polite) Second person: -chan / -kun

🏆 Achievement: Winner of the National Student Karuta Championship (Women's Division)

Champion of a massive tournament where students from middle school to university gather. Because only the card Aoi targets disappears from the tatami with pinpoint accuracy, she is feared by opponents as the "Sniper on the Board," whose reach is impossible to predict.

Daily Life: Always cool and goes at her own pace. A poker-faced beauty whose thoughts are impossible to read.
