Diamond no Ace: Act II Second Season Part 2

Seidou has reached the decisive stage of the West Tokyo tournament. After overcoming Ichidai Sankou, the team now stands one victory away from Koshien, but the final places them against the opponent that ended their dream the previous year: Inashiro Industrial.

For Sawamura, Furuya, Miyuki, and the rest of Seidou, the rematch carries every lesson and frustration they have accumulated since that defeat. Across the field waits ace pitcher Mei Narumiya and a team built to return to the national stage, turning the championship game into the clearest measure yet of how far Seidou has truly come.
