ComiXology is listing the first volumes of Yūji Terajima’s Ace of the Diamond and Hiroki Endo’s All-Rounder Meguru manga for digital release on March 7, 2017 from Kodansha Comics.
The story of Ace of the Diamond is described as:
Eijun Sawamura had his heart set on the middle-school national baseball championships. But his team is eliminated thanks to a wild pitch thrown by Eijun himself. He’s planning to go to high school with his teammates and try again next year when he’s scouted by the famous Seido High School Baseball team. When he goes for a campus visit, he finds himself on the receiving end of a baptism by fire. His experience forming a battery with up-and-coming catcher Miyuki rekindles his passion for baseball.
Terajima launched the manga in Kodansha’s Weekly Shōnen Magazine in 2006, and began the second part, Ace of Diamond Act II, in August 2015. The original manga won the shōnen category of the 34th Kodansha Manga Awards in 2010.
The story of All-Rounder Meguru is described as:
High schooler and budding Shooto mixed martial arts fighter, Meguru Takayanagi, reunites with his old friend from grade school, Takashi Segawa, in the ring for the first time in seven years. However, while the two used to be good friends, due to the difference in their upbringings, Takashi now sees Meguru as an enemy. Without a moment of joy to commemorate their reunion, the old friends’ match begins.
The manga ran in Kodansha’s Evening magazine from 2008 to 2016.
