Because of the legend left by Tatsuya Uesugi, Meisei Academy High School was well-known for their strong baseball team. But 26 years after their glory, the team has not been able to keep their record and has since lost their fame. Two stepbrothers, Souichirou and Touma Tachibana, aim to revive of the once-strong Meisei Academy baseball team and enter the National High School Baseball Championship. Souichirou and Touma are second years in Meisei Academy Middle School. Both boys are talented baseball players. Souichirou has shown excellent skill as a catcher and batter. Though having an extraordinary skill as a pitcher, Touma no longer pitches due to a certain reason. Once the two enter high school, they pair as a battery and aim to enter the National High School Baseball Championship!
"30 years ago, Meisei High School's baseball team won the much sought after Koshien Tournament, but haven't come close since. As the new school year at Meisei Junior High School begins, brothers Touma and Souichirou Tachibana start practicing in secret."
"To everyone's surprise, Daisuke pitches a whole winning game despite only having practiced with the team for an hour. The Meisei team goes to the Tokyo Tournament, but Daisuke doesn't show up until the game is well under way."
"Meisei loses their match to Seinan after Nikaidou has a bad inning. Nishimura, Seinan's pitcher, tries to convince the Tachibana brothers to transfer to his team."
"The mystery of Daisuke's odd practice attendance pattern is revealed. The new season brings changes to the Meisei baseball team, including a new Manager!"
"Spring brings a new baseball season. The brothers are in high school now, playing under their new manager Ooyama. Ooyama is reluctant to let Touma pitch with the upperclassmen, but he quickly changes his tune after watching Touma pitch."
"A big storm blows in sending everyone running for cover, and Nan reminisces about his near-death experience. Souichirou meets Hiroki Mita, a star player from another school and Arisa's big brother."
"All the boys love Otomi. Touma gets a letter from Haruka, inviting him on \u201ca walk.\u201d They travel for hours to solve a riddle, then get stuck in the middle of nowhere. While everyone else waits at the Tachibana residence, Ooyama reveals that Haruka and Touma met when they were three, and she threw soda in his face."
"Punch is feeling under the weather. Ooyama learns where Tou picked up his pitching skills. The history of the Tachibana family and Meisei\u2019s number 1 jersey is revealed."
"For info on the history of the Meisei High School Baseball Club, Ramen Dragon is the place to be. Sou and Otomi's ties to the team go back farther than they knew."
"It\u2019s the bottom of the eighth, and Meisei is down by one. Will their dream of reaching Koshien once again be crushed in the first round of the East Tokyo Tournament?"
"With Sou and Tou powering the team through the early rounds of the tournament, Meisei's story draws fans from far and wide. Ryou learns that his family and Otomi\u2019s are more alike than he knew."
"Nobody expected Meisei to reach the quarterfinals \u2013 not even their manager. With Touma resting his arm out in left field, can the bullpen carry the team against the hard-hitting offense of Kaiou Nishi?"
"Meisei's path to Koshien is in peril as they face off against Kaiou Nishi. Do they have the skill\u2014and the luck\u2014to survive to the semifinals?"
"Now comes the highly anticipated semifinal match between Meisei and Toushu! The rising rookie battery of Touma and Souichiro faces off once more against the unshakeable prodigy, Hiroki Mita, in a tense pitchers' duel with the tournament on the line."
"Six innings in, the semifinal match between Meisei and Toushu remains scoreless. Under the burning sun and the pressure of the crowd, which team's star pitcher will reach his limit first?"
"Meisei and Toushu's war of attrition has entered extra innings, neither pitcher allowing a single run. With Toushu playing in unfamiliar category, and Touma seemingly reaching a new level on the mound, will this be the year Meisei returns to Koshien?"
"The mysterious stranger staying with the Tachibanas decides he wants to go for coffee, but the coffee shop he is taken to is nothing like the one he has vague memories of from a time long past."
"Kenjo High challenges Meisei to a practice match to try to get their measure, but Ooyama isn't happy about the idea of showing off his team's new potential..."
"While Masaki and Harada reflect on the tragedies Meisei has faced in the past, Ooyama organizes an intra-team competition with team positions and ramen on the line."
"What should be an easy win for Ooyama's team in the scrimmage grows more complicated when Touma can't throw his full heat to an inexperienced catcher."
"The qualifiers for the summer tournament at Koshien are finally underway. Due to being seeded, Meisei High gets a bye for the first and second rounds, meaning they have to wait to find out who their first opponent will be."
"Meisei High plays Hiryuu North, a \"delinquent\" team with something to prove. When Natsuno starts looking shaky on the mound, Ooyama considers relieving him, but..."
"Old emotions and fears rise to the fore as Meisei prepares to face its next opponent: the same school they were playing when Souichirou's father received his career-ending injury."
"It's Kenjo versus Toushu and Seinan versus Meisei for the East Tokyo Championship semifinals. Nishimura hopes that a big win will make his father's dream come true."
"Meisei overcomes their semifinal opponents to set up a mouthwatering final with Kenjo with a ticket to Koshien on the line, but someone seems to be missing from the celebrations..."
"Harada is still struggling to overcome his amnesia. He tries his hand at a former pastime of his, plus reconnects with an old school chum in the hopes that this might trigger some memories."
