Yo I completely respect what you are saying but I want to add one thing.
I think you are overly focused on the fact that its written by Ryukishi.
I mean, if you wouldn’t know it was written by him maybe you would have another perspective of looking at it? I have to agree with lucia going against the plot progression, but on the other hand I like the style of Lucia’s route. It’s more action-ish but I think it fits Lucia’s route. Tbh I cant imagine her route being different than this… or maybe I can but have no idea what it would look like lol.
I think this servers as a get-to-know information what is happening in the background and that you will kinda understand the situation - yeah get to know other chars well. I think that is a really good thing because the more you are dragged and know more info, the more it will affect you in an emotinal way imo.
