I’m going through Ageha’s route now, and it’s quite bizarre. I googled it to see if it was just me but it looks like it was largely rewritten for context because of the removal of the h-scenes. The translation and presentation of the story is (to me) odd. I guess this one really does benefit from the Restoration patch. It’s a bit unfortunate if that route is chosen first ahead of Kotori.
EDIT: I ended up skipping most of Ageha’s route in the end as it got too painful, nonetheless I think I did get the gist of what was going on but 10+ hours of it was too much for me. Trouble for me is that the glider story seems to be pushed back far too much - but saying that it does add a little to Ageha and Aoi’s back story if you chose or landed on Kotori’s route first.
EDIT #2
Asa & Yoru - could be considered a minor spoiler so identical twins and I found it a bit hard not to draw some parallels with the Ryou/Kyou love triangle this is quite a fun route though it doesn’t really add much to the overall story. There is a combination of the routes up to a point, we do go through some of the usual tropes, e.g. Polar Opposite Twins, Different as Night and Day, and I don’t know if the h-scenes go full on Twin Threesome Fantasy but it seems from hints on the Steam version it might end up that way!
