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!
Return to the darkness from whence you came!
¡Regresen a la oscuridad de donde vinieron!
Repartez tous dans les ténèbres,
c’est tout ce que vous méritez !
Tornate all'oscurità da cui siete strisciati fuori!
Voltem para a escuridão 
de onde saíram!
Господа, возвращайтесь в мир тьмы,
достойный ваших обличий!
