Ena Soida 19 years old Lustrous blonde hair and blue eyes. She wears a white jacket, the uniform for Edamame Discharge public relations. The only daughter of the CEO of "Soy Mega-Corp," the company that popularized Edamame Discharge, and the face of the sport. She has a bright, brisk, and spirited personality. She is high-minded and strict with both herself and others, but is always serious about trying to be kind to people. She has a good rivalry with Yutaka. However, he is a "no" as a man. She says quiet men aren't her type. She is a highly skilled Edamame Discharger herself, a master of divine techniques who can read the flow of air from weather, humidity, and temperature to send edamame flying on the wind. The "Kamikaze" Edamame Discharger who takes the wind as her ally. A hardcore hater of natto.

Midori Shiomi 15 years old Pale green medium-length hair. Wears a blouse and a skirt with floral patterns on the hem. The daughter of the plant manager at "Shio-aji," the country's largest edamame cultivation plant. A cheerful, sunny, and healthy girl who grew up loving edamame and being loved by them. She is Toko's childhood friend. Being at the heart of the edamame production that forms the foundation of the city, she has many connections despite her youth. If you're lost, it might be a good idea to have her choose an opponent for you. She dislikes the tense atmosphere of competition, so she doesn't participate in Edamame Discharge and is a spectator. She enjoys seeing the world get excited over edamame. She loves all soy products.

Toko Tofuna 17 years old Black hair cut short, wearing the uniform of the academy in Otsumami. Midori's childhood friend. The daughter of the head priest at Daizudera Temple. A polite and cool girl raised by a strict father. She met Midori when they were young and stepped into the world of Edamame Discharge in place of her friend, who dislikes competition. Her weapon is her eye for edamame developed through her friendship with Midori. She is the "Keigan" (Insightful Eye) Edamame Discharger who can instantly find the best-flying bean out of a hundred. As a child of a temple that preaches "Soybeans must be as they are," she does not touch soy products that aren't bean-shaped, such as tofu, soy milk, or soy protein.

Yutaka Misogi 20 years old. Suit-clad with neatly styled brown hair. The young ace of the miso industry and a new hero in the Edamame Discharge world. He has achieved excellent results in numerous tournaments and is on the elite track of Edamame Discharge. He is always a calm and collected cool guy, but he is a passionate and kind gambler at heart. He has a good rivalry with Ena, but she is a "no" as a woman. He says he prefers more ladylike women. In the world of Edamame Discharge, where the one who flings the bean farthest gets everything, he is famous for never making demands of the losers despite his constant victories. To him, the match itself is the purpose, and victory itself is the reward. A "Gentle Edamame Discharger" expected to gain even more popularity when he hits his thirties. When it comes to ramen, he prefers soy sauce over miso.

Nako Mochiki 14 years old. Pale silver hair tied in twin tails, wearing the uniform of the academy in Otsumami. A quiet girl who stands on the outskirts of town. Her parents fight constantly, so she has lost her place at home and stays at the cafe "Mameyaka" run by her grandparents. Perhaps because of this, she lacks emotional expression and is taciturn. She shows a slight flicker of emotion when participating in Edamame Discharge, which she started by joining the adults who were obsessed with it. Her grandparents tell her to stop because it's dangerous, but driven by impulse, she waits for Edamame Discharge opponents on the outskirts of town. With a natural talent for high-precision power adjustment, she can fling any edamame the exact same distance. A tiny, precision Edamame Discharger. She hates roasted soybean flour (kinako) because it makes her choke. The kinako lattes her grandpa makes are the exception.

Yokutobu Nankasugoi 55 years old. A large-hearted, good-natured man. A stout figure dressed in green Japanese clothing. The strongest active Edamame Discharger and the world record holder for edamame discharge distance. The edamame he discharges fly... somehow, incredibly far. He is eagerly waiting for the birth of a new Edamame Discharge champion who can surpass him. If you can defeat him, you will be the best in the world in name and reality. You will likely obtain everything in Otsumami. He regularly uses whey protein.
