Ashito is having a hard time mastering the basic “kill it, then kick it” technique. Seeing the look of desperation on Ashito’s face as he heads out to a solo nighttime training, Togashi agrees to teach him the true meaning of the “kill it, then kick it” technique. However, Togashi’s explanations are abstract and vague. They get frustrated at each other, but Ashito gets a hint when Togashi finally demonstrates it.
You "open" your body to 
widen your field of vision
عليك أن "تفتح" جسدك لتوسّع نطاق رؤيتك
Mit offen meint er das Blickfeld.
Se abre el cuerpo
para ampliar el campo de visión
Se abre el cuerpo
para ampliar el campo de visión
Il parlait de mon champ de vision.
Quando parlava di "aperto", 
intendeva la visione di campo!
Esse "aberto" é sobre o seu campo de visão
«Открыто» —
это про «смотреть по сторонам»!
