Ace of Diamond Act II -Second Season- is a TV anime from 2026, first released in Fall 2026. It belongs to the Sports genre and is listed as currently airing. The summary above is written by the AnimeYug team in our own words.
Story & Plot
Eijun Sawamura came to Seido High, a Tokyo baseball powerhouse, to follow catcher Kazuya Miyuki and become the team's ace. Years on, he is still chasing that title, sharing the mound with the harder-throwing Satoru Furuya and learning, game by game, what an ace actually carries.
Act II -Second Season- follows Seido through the spring invitational at Koshien and into the West Tokyo summer tournament, the road that decides who goes back to Koshien in the summer. Every round raises the price: rival schools know Seido's pitchers now, and at the end of the road waits Inashiro Industrial and its ace, Mei Narumiya, the pitcher who has beaten Seido when it mattered most.
This is a team story as much as Sawamura's. Miyuki's game-calling, Kuramochi's speed, Haruichi's bat and a dugout full of players fighting for nine starting spots all get their moments, because at Seido, nobody's place is safe.
