Masahiro Saki (茶木 正広, Saki Masahiro) is a second year small forward who plays for Kuzuryū High. He is a substitute player and can also play a small role of point guard when the team needs him. Everyone on the Kuzu-High calls him 'Chucky' or 'Chucky sempai' by Sora, Tobi and Shigeyoshi.
Saki is about 171 cm. He has long brown hair that ends before his shoulders. He wears glasses and has dark brown eyes. His jersey number is 6 and wears pair of white sneakers which has blue out-soles.
Similar to Yasuhara and Nabe, Chucky had no prior experience in basketball. He started taking the sport seriously when his delinquent colleagues became determined on honing their basketball skills. In the midst of the training camp, Saki and Nabe got into a serious argument with Tobi. Kenji scolded them for not taking the basketball practice sessions seriously. Upon hearing that both left the school facility. To test out their basketball skills Saki and Nabe participated in a friendly match against junior high kids at a nearby park. Due to their over confidence and inadequate basketball skills both lost the game. After the match one of the middle school kids questioned them and asked if they were really members of a basketball team. Upon hearing that, Saki and Nabe lost their will and confidence in playing the sport. Sora later confronted them and asked as to why they left the training camp. Chucky stated, I have lost my passion on playing basketball because at the current moment I am unable to find my role as a player on the team, hence I don’t find this sport interesting anymore.
While walking across the nearby park, Chucky and Nabe eavesdropped on a conversation between the middle school kid and his girlfriend. She stated, in my opinion people who play basketball look awesome and cool. Upon hearing that Chucky and Nabe were shocked and amazed to see such a young kid achieve so much in life. Through sheer hard work and determination he had taken his game to the next level, which was appreciated by his girlfriend. If this junior high kid can achieve this much in his life why can't we. They thought that improving our basketball skills we can also become popular among girls. The subsequent day both challenged the junior high kids to another basketball match. With assistance from Sora, they won the game and returned to the training camp.
His field goal percentage and vision aren't great but is still a reliable backup because of his talent in defense. He can also fill in as an extra Forward or Guard. Alongside Nabeshima, he has become great at helping teammates through screens.
