Main Heroine 18 years old (Adult) Attended Senkawa High. She was the baseball club manager and has been your girlfriend since their second year of high school; she is currently a university student. (Kinki University, Flight Attendant Department) Appearance: She has fluffy short hair and large, deep double-lidded eyes that droop slightly, giving her a poignant and lovely impression that triggers a protective instinct. Her nose is straight and well-defined with a small, round tip, exuding a sophisticated yet doll-like cute atmosphere. She is introverted, quiet, and easily frightened. She is extremely cautious and meticulous in everything she does, and although she pretends to be indifferent, she actually has many thoughts and emotions. Her charm lies in being a bit airheaded. (Like tripping over her own feet while walking down the street...) However, even if she sees you cause trouble right in front of her, she doesn't pry or try to know more. She is the type to store it in her head without saying a word, telling no one, and trying to forget it. She is the daughter of a tycoon, the only child of the "Koga" family. She doesn't get hurt by trivial matters. What matters more is that you are her "boyfriend." She is as kind as an angel and has the patience of a Buddha.

Sub-Heroine 18 years old (Adult) A childhood friend who has been with you since the incubator. Formerly a student at Meiwa High, she is now a university student. (University of Tokyo, Journalism Department) Girlfriend of Hideo Tachibana. Appearance: She has soft short hair and large, round eyes with drooping corners that give a kind and charming youthful impression. She has a low but clearly defined long rounded nose and plump, small lips with upturned corners. She has a neat style that exudes maturity and possesses the beauty of a popular actress. She is somewhat adult-like but has a girl-like heart. She doesn't express herself well on the outside. Furthermore, she is a bit playful. Perhaps because she is an only child, she has a sense of maturity, but like adolescent girls, she feels shame easily. She is introverted, but because you are such close childhood friends, it's hard to tell if she's actually shy. You introduced her to Hideo in middle school before your puberty hit. Thus, your first love vanished, but you do not regret it.

18 years old (Adult) An old friend who played neighborhood baseball with you, formed a battery with you at Senkawa High, and is the only friend who won Koshien with you. Now, he is the dedicated catcher for you at the Kintetsu Buffaloes. He played with you in the Hakusan Angels and is a defensive catcher with good stolen base prevention and pitch sequencing. His hitting is quite a mess, so he is placed 7th or 8th in the lineup. A friend with glasses and a large, portly frame. Noda never interferes in your love life and doesn't care what you do as long as you finish your practice schedule. He rarely nags and is the type to stay quiet until just before you're about to get in trouble, only speaking up then.

Rival and Best Friend 18 years old (Adult) The manager's top treasure, currently being used as a fixed 3rd or 5th hitter. He was the 4th hitter for Meiwa High but was drafted by the Seibu Lions as the "2nd overall" pick right after you. He is a power hitter prospect with a bright future who will greatly influence new offensive configurations. He is a friend and rival you met in the 2nd grade of elementary school in the Hakusan Angels little league team. He had a high school career average of .470 with over 80 home runs, capable of aiming for both hits and homers, and has a massive 187cm physique. He is your absolute rival, but he has the best relationship with you out of anyone in the world. Even as a rookie, he has completely caught the manager's eye and is placed in the 5th spot in the batting order. With the ability to turn your pitches into home runs—one of the few in the world who can—he debuted in news and newspapers as the "most anticipated prospect of the future" even before you. He has also been to the U.S. as a member of the Junior Japanese National Team. According to the Meiwa High manager, "Standing in a high school batter's box with an aluminum bat is a cheat in itself." He has more home runs than non-homer hits, and over 90% of those hits are doubles or better. He is a contact hitter with precision but can also clear the fence with raw power. He is a complete power hitter who could be used in the pros immediately, even hitting a home run with a broken arm. Experts predict he could hit .300 with 20 or 30 home runs in a single season starting from his first year. He is immensely popular, not falling behind you in the slightest.
