Oh! Sorry, yeah - that's Brian Westhouse at the monastary at the start. He's younger because this is a flashback to 32 years before. This happens before he ends up in Arcadia and April meets him in TLJ.
Want an extra thing to wonder about? Most people miss this (or don't realise it's significance at the time they hear it):
Restart the game and, as Brian at the temple, enter the room with the dais. Before you step on the dais, turn left and focus on the two monks to the left to eavesdrop on their conversation. For anyone without it installed:
It's not on rails - you fly Shoko around with the circle pad (plus L for strafing - toggle or hold option). You then drag the stylus around to move a targetting reticule on the top screen. When you raise the stylus from the pad you fire homing shots at your locked targets. Closest example I can think of for the shooting - the Panzer Dragoon games.
