Touya and Minori and the rest of the players in the training camp are hitting a wall with the way they fight.  And Minori's suggestion is that they introduce themselves to one another!
as a man, you must promise to do that!
¡Es una promesa de hombres!
Tu dois en faire le serment !
sei un ometto, perciò devi giurarlo!
como homem, deve prometer fazer isso!
