Yeah it's from mla I'm playing it again untranslated and this part was on a txt inside the game and it didn't make much sense to me.
I got the idea in my head but it's really hard to put it into words that express the same thing in english, "behold" sounds like a magician talking but "look" sounds too bland and generic. She is like trying to say, "look to your childs marimo they are leaving/marching to the war, look how well you trained them, feel proud." She is saying all of that but there is not way to translate it
Still the original one "Look, Marimo......they're leaving now." was kinda lacking.
