Username: ~Kaoru Hitachiin~
Name: Rin Matsuoka
Nickname: Rin, Rin-chan
Age:17
Personality:When he was young, Rin showed a lot of passion and competitiveness for swimming, as well as an interest in teamwork. After years passed, his ideals about swimming drastically changed. He does not care that much about the trophy they won during their elementary days.As the Iwatobi High School Swim Club continues to practice and have fun together, Rin often times catches glimpses of them during their practices and is notably morose when he sees how happy they are together while he stands there alone. The teenager aspires to make his father's dream of becoming an Olympic swimmer come true and has detached himself from everyone while working toward that particular goal. At times, Rin displays a softer side, as he is shown to still harbor concern for his friends' well-being and he acts like a mentor toward his younger sister Gou and teammate Nitori. Rin is conflicted emotionally, but his pride as a swimmer is used to mask his insecurities.
History: Rin's father died when Rin was very young; his father was a swimmer who had dreamed of going to the Olympics but had to give-up his goal and become a fisherman. Due to a tragic incident (a storm), his father drowned three kilometers off the coast along with the rest of his crew. Rin stated that he has very few memories of his father and cannot even recall what his father looked like, as his father would be gone for days while out fishing. Rin decided to try and become an Olympic swimmer because he believes that by following this path, he will be able to see his father's face. Rin puts his swimming goggles on in the same way his father did (by pulling the strap back and letting it snap back onto the back of his swim cap).Rin joined the Iwatobi Swimming Club prior to leaving for Australia because that was his father's old club, where his father and his teammates had won the relay. Rin wanted to make a team and win the relay to emulate his father as he started down the path of becoming an Olympic swimmer.

Username: above^^
Name: Rei Ryugazaki
Nicknames: Rei-chan
Age:15 almost 16
Personality:Rei is considered handsome and intelligent because of his looks and good grades. He also has a penchant for beautiful things and the thought of exuding anything but beauty through his actions, causes him to dramatically lose his cool.
Rei may initially seem like a calm and composed character, but he is in actuality quite comical in a sense that he sometimes lets his confidence get the better of him. He is however, depicted to be a hardworking and determined individual, unwilling to relent to his inability to swim despite several failed attempts.
Rei has a theoretical approach when it comes to sports, as he usually calculates distance, angle, and other factors in his mind before actually making an attempt. Because of his rigid nature, he has a tendency to overlook the fun and enjoyment that comes with the activity. As Haruka told Rei, he needed to be "free" in order to swim properly, because he is constantly calculating and underestimating the water.
History: i would rather not talking about it
Is this good?))
