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!
It seems to make the damage 
dealt by any non-warrior class
Wenn es gewirkt wurde,
soll es den Schaden verringern,
Hace que el daño causado por una 
clase no guerrera parezca menor.
Grâce à ce chant, les dommages
infligés par des personnes
A quanto pare, fa generare a ogni danno 
inflitto dalle classi non guerriere
Faz o dano causado por 
classes não-guerreiras
