Invincible Mentality (3x37)

Air date: Dec 10, 2019

Narumiya, who pitched from the 7th inning, struck out the fourth batter of the American Wind Youth, Carlyle, in a straight strikeout. However, the bat that cut the sky daringly hits the catcher Inui's head. Director Kunitomo decides to replace Inui. Instead, a forbidden battery called Miyuki and Narumiya wearing masks is born. On the other hand, even at Seido High School, which had a practice match with Yamamori Gakuin, an accident attacks Ono, who continued to play vigorously to fill the absence of Miyuki.
