The second semifinal takes place as Inashiro Vocational battles a surprise dark horse in Sakurazawa High. Sakurazawa had 20 consecutive seasons of first round exits until some surprise first years arrived. Inamooto Masaaki, Hitokoro Yoshimi, and Nagao Akira arrived. Akira brought in the same enthusiasm as Sawamura, but while his pitch looked super slow, the erratic pattern confused many payers. Masaaki surprises everyone by getting the top of Inashiro's order out with his knuckle ball, but when Mei takes the mound and strikes out the side Sakurazawa begins to realize how little a chance they have of advancing. This episode covers the second half of chapter 134 through chapter 136.
