Or to put it simply, since Nanatsu no Taizai is in the Middle Ages setting with almost no sign of Japanese influence in the series, most calling out of attacks are all in English and btw there are no honorifics like san, sama, kun, dechi, chan, tan, dono, etc. in this manga unlike most other series that frequently uses them all the time. You can tell from every chapter that none of any character spoke those words at all.
