Regarding party speculation for CS3, here's what we know so far from Kondo's Dengeki interview:
- The story picks up 1.5 years after the CS2 ending, Class VII has graduated and everyone has gone their separate ways (translation: this is just like how CS2 starts, with everyone split up and Rean on his own)
- Rean is still working under Osborne trying to find his own way. Based on the key art and the screens, he's probably still paired up with Altina
- Sara is no longer an instructor at Thors
- The two new characters in the key visual seem to be Thors students, but he doesn't comment on the actual nature of the uniform, the girl with green hair in one of the screens is a character who has a connection to Rean as well (translation: more harem bait zzzzzzzzzz)
- There will be returning characters from the Liberl games who will join the party
- A certain "someone" from the Crossbell games will have a role in the story
- Rean's remaining mysteries will be revealed
- The new Brave Order system has to do with commands Rean can issue so he's definitely the main character again lol
Here's what we can assume based on stuff from CS2 as well:
- Fie still has a big role to play if they're going to do story stuff regarding Zephyr
- Laura and Gauis are probably going to be involved in the story at some point if they want the rivalries to play out with those two generals they introduced in CS2
- If Altina is a party member, it seems unlikely Millium will be, but she'll probably play a role in Altina's storyline
- Elliot sucks no one gives a fuck about him (haha made you read!!!)
Thanks for this!
As for the CS2 connection
It's pretty obvious Fie will important even if she's not playable as Zephyr tell her they want to bring their boss back in the last dungeon of CSII. I guess it might be linked to Osborne resurrection?
Altina is no surprise seems they were together in the Divertissement Epilgoue. I guess the main character from the Crossbell games will Be Lloyd as he asks Rean his name and vow to remember it
Sara not being a teacher anymore was already known. She goes back to being a bracer with Toval in the ending and you can see Fie with them in one of the picture during the credits
Oliver better be playable in this one and I hope Angela and Sharon are back they were the best part of CSII
