Load the cleared saved game file by pressing Triangle
to start the game with new options. You may also load the cleared
game file normally to resume the game at the room prior to the
final Boss. There will now be a clown NPC in the room. Talk
to him, then return to where Rutee was first encountered to find
the clown again. Talk to him and select the first option to enter
a bonus dungeon. Each floor completed will give you EX points
that are used to buy items from the clown, via his third dialogue
option.
