Tsutsui is the nerdy and kind hearted Haze junior high school Go club president who uses a play book
while playing in tournaments. While he is not a strong Go player and doesnt play too well, he loves
the game and plays with a positive attitude. Hikaru first meets Tsutsui in a Terakoya fair (its
Japanese food; octopus dumplings) where he would give out prizes to individuals who solved Go
puzzles in Kouyo Tonyas book. At that time, Tsutusi was the only member of the Go club and was
trying to recruit other members so his Go club can compete in tournaments with other junior high
schools.
