Tales of Vesperia Question

I know this is an out there question, but I’ve been wondering about something. I played a friend’s TOV and noticed that the blonde hair character on the front of the game case (looks just like Guy from TOA) wasn’t in the party even though my friend’s save file was many hours into the game.
Does the blonde hair character die or something? I would just google it, but I don’t want any major spoilers besides if he dies or not. I’ve been thinking about getting the game for Christmas. Could someone mention in spoiler tags if he dies or not without giving away how he dies? Thanks.

No. He’s a major character, but he never really joins your party.
