【Name】 Kurumi Sakurai 【Age】 16 【Personality】 A bright, energetic, and easygoing girl. She doesn't worry about the details and charges ahead with a "Well, it'll work out somehow!" spirit. Despite acting with full confidence, she's actually quite reckless.

【Speech Style/Catchphrases】 "Wait, isn't this just like Donjara?" "I know it, I know it! Probably!" "If I just collect the same ones, it's strong, right?"

【Appearance】 A bright and active-looking girl with brown hair tied in twin tails with large red ribbons. She is expressive and has an air of someone who came to play, even in her school uniform.

【Mahjong Knowledge】 She has zero actual Mahjong experience, having only played Donjara as a child. She only knows that she should "collect similar tiles" and has no knowledge of yaku, point calculation, or calls like Pon/Chi. Even so, she thinks, "I've played Donjara, so I'll probably be fine!"

【Name】 Makoto Saito 【Age】 17

【Personality】 An ordinary high school student you could find anywhere. He's not particularly sharp or airheaded, but a sensible person who is easily influenced by his surroundings. Even when he doesn't understand something, he doesn't think deeply, assuming, "Well, it's probably right."

【Speech Style/Catchphrases】 "A 'Pon' is for times like this, right?" "I at least know what a 'Ron' is." "...This is right, probably?"

【Appearance】 A male high school student with black hair and a very average face. He wears his school uniform and has no distinguishing features.

【Mahjong Knowledge】 He knows the words "Pon, Chi, Kan, Ron" and their general usage. However, he knows absolutely no yaku and believes he can call Ron as long as the shapes are aligned. He has no understanding of point calculation or detailed rules.

【Name】 Go Kurosaki 【Age】 18

【Personality】 Quiet and taciturn. He is always calm and rarely changes his expression. He emits a sharp gaze and a strange sense of intimidation; just sitting silently at the table makes him look like a veteran gambler.

【Speech Style/Catchphrases】 "...I see." "So that's how it is..." "............"

【Appearance】 A tall man with black hair swept back. He has a stern face, sharp eyes, and a sturdy build. The way he glares at the Mahjong table gives him a strange aura of authority, making him look like a powerhouse no matter how you see him.

【Mahjong Knowledge】 Absolute zero. He doesn't know the types of tiles, yaku, or point calculation, and doesn't even know the meaning of Pon, Chi, or Ron. He doesn't even know what constitutes a win. However, because he carries himself with such dignity, those around him often misunderstand and think he is "plotting some terrifying strategy."

【Name】 MC 【Age】 35

【Personality】 A cheerful, high-tension tournament host. Once he grabs the microphone, he provides play-by-play commentary as if everything is a major incident, hyping up the venue unnecessarily. However, he actually knows nothing about the rules of Mahjong.

【Speech Style/Catchphrases】 "And nowww! Things have taken an incredible turn!!" "Uh... this is... well... um..." "Yes, it's decided!! That's 5,000 points!!"
