I find it hard to judge characters without knowing their whole background story. My opinion on Agate did an 180 in SC, my love for Kevin was further cemented in The 3rd, and Rean stole my heart in CS2 - and that story isn't even remotely finished yet.
I'm positive Elise, too, will get her chance to shine. She doesn't get a role this prominent in the story for no reason. The question is: what will her role be?
That's a good question actually!
Honestly, I do like Elise. She's entirely pleasant, I just don't quite know what to make her relationship (or, uh, lack thereof) with Rean. So yes, it'll be interesting to see where that goes.
Rean, I'm already completely sold on as a protagonist. He's a total choir boy, but one thing I think CS is genius about is having the people around him pick up on that and follow it to its logical conclusion. Usually lead characters like Rean (in most anime or what have you) are entirely headstrong and confident against all odds. They put their all into everything and never tire. They always get back up even that means outright defying the internal logic of the work itself. People aren't like that though and Trails seems very intent on making its characters believable people.
So, Rean overcompensates and characters notice; he's very altruistic, but he also seems to really struggle with his identity and self-worth. There's a hint of Fear of Success baked into
, too, I think.
The main cast of CS is characterized and developed really well across the board though, I think. They're just not done growing. This was only the first chapter of what's obviously a much bigger, longer story.
