The standout member of the Bando Spiders is a second-year student named Sasaki Koutarou. He is known for his exceptional kicking skills and has never missed a try-for-point kick, even when attempting to kick a soft drink can into a rubbish bin from a bridge railing. His accuracy as a kicker is so impressive that it can be used against him since it's easy to predict where his kicks will land and they can then be returned. In the match against Deimon, Koutarou stresses out and misses a field goal attempt, which could have won the game.
Koutarou is known for his famous quote "That's smart" (Smart daze) and is often seen combing his hair whenever he has time, even during matches. He dislikes Akaba Hayato because he keeps talking about music. Koutarou used up a time-out just to explain the history of the Spiders to Deimon. His last name is the same as a famous samurai, Sasaki Koujiro, who was a rival of Miyamoto Musashi. He asked Bandos manager, Sawai Juri, who is also his childhood friend to go out with him three times, but she refused with "Whatever, stop saying stupid things, moron!" However, it's interesting to note that in a poll conducted in Japan, Koutarou was the only non-Deimon player to win in a showdown against Taki.
