Aired on February 2, 2013

Harada and two Shiranami Society women attend the regional tournament semi-final where Mizusawa faces Homei, advised by Tsugobuchi. Tsugobuchi instructs his team to psychologically distract Taichi, who begins to doubt his abilities. Mochida notes that the tournament uses a different reader each round this year. Miyauchi also attends. When the air conditioner over the Mizusawa match breaks, multiple spectators including Miyauchi, Sumire, Kana, Kana's mother, and Chihaya provide towels. Sumire observes that Chihaya watches Taichi as intently as he watches her, then goes to scout the Hokuou match. Taichi recovers his composure, wins the match, and secures the round for Mizusawa.
