Does the game end after the last boss?

I would like to clear all mini bosses and not sure if I have this option after ending the game's main story.

So here is the question:

Is it possible to continue playing and fight mini-bosses after the final "story"-boss?


Solution 1:

Once you beat the final boss of your route, you don't go straight to new game+. You can continue to play until you choose to go to ng+ at the dilapidated temple idol.
