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!
The first and last members in 
line cover each other's view,
Das erste und letzte Glied decken dabei
gegenseitig ihre toten Winkel,
El primero y el último 
miembro en la línea cubren
Ceux de devant et de derrière
couvrent les angles morts.
Il primo e l'ultimo membro del gruppo 
si coprono a vicenda,
O primeiro e o último membro da
 fila cobrem o campo de visão,
Так авангард с арьергардом
могут прикрыть все слепые зоны.
