Fight 3 is the 3rd chapter of the Tenjou Tenge manga series.
Masataka told Souichiro that if he lands a hit, he is the winner and Souichiro took him on. Aya recalled a conversation with Souichiro where she asked him to not lose. Masataka and Souichiro kept fighting with Masataka easily blocking and hitting Souichiro. As he was about to lose, Aya yelled at him, saying that her husband can't loose to a second rate martial artist and Souichiro pulled himself. But hearing that insult, Masataka lost it and as he attacked, he felt for Souichiro's petty trick and Souichiro managed to land a hit.
