After completing the 3 routes in the game, you can access the shop by talking to a strange woman at the base camp. Here, you can buy all the non story related achievements/trophies with in-game currency.
To the best of my knowledge, this is the only game that offers this option. IIRC, reception to this was mixed: in one hand, there's no point in achievements/trophies if you can just buy them. On the other hand, making people realize that achievements/trophies are pointless was the actual point of the shop.
