The Plucky Squire

Just an FYI that this will pop when you complete the game in either Story or Adventure mode (i.e. you don't specifically need to select 'Story' mode when starting the game to get this trophy).

EDIT: Ignore the downvote(s) as I can 100% confirm that you do get this trophy when playing in either Adventure mode or Story mode. This game has started life a little glitchy, so if you've played in Adventure mode (or even in Story mode) and for some reason haven't had this trophy pop, then you may want to try reloading your last save and beat the final boss again or wait for a patch to improve the overall trophy registration of the game (and then beat the final boss again).
