Mei attempts to explain something very important to Sagiri's party in the forest. Shion tries to explain how he interacts with the world to Nurugai. A mysterious servant of the Tensen tries to explain why Aza Chobe and Toma shouldn't escape.
Don't swing your left arm wildly. 
Be aware of its position.

Greif nicht blindlings an,
sondern bewege bewusst die linke Hand.
No se balancea sin sentido. Se sostiene

Não balance demais seu braço esquerdo.
Concentre-se na posição dele.
Не размахивай мечом лишний раз,
следи, чтобы левая рука была в центре.
