Witnessing the Dojo Flashback grants the ‘Treasure Your Friends’ Trophy/Achievement. Here is how to unlock it!
This MUST be triggered right at the start of the game, after the automatic cutscene with Fuku-San in which the games takes you back out of the Dojo.
Immediately head back in to the Dojo and try to zoom and scan on the parchment on the left wall (above the wall Fuku-San is facing)
