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!
Just let yourself be happy, Rudy.
Relájate y alégrate, Rudy.
Arrête de cacher ta joie, Rudy.
E dai, Rudy, esulta e basta!
Relaxe e alegre-se, Rudy.
Хватит выделываться! Просто порадуйся!
