Loqi is a lefty!
what tipped me off was the red fabric he wears on his arm that bears the Niflheim empire insignia, usually decorative pieces are worn on the non-dominant side of the body so they don’t get in the way. Shuffling through the screenshots confirmed it!
exhibit A) he has his sword hanging on his right hip where it’s easier to grab with his left
exhibit B) grabs Noctis to throw him off using his left hand even though his right is closer to the spot he yanks on
Exhibit C) signals for the soldiers to attack with his left hand
that’s pretty neat!
