Sapporo Jail – Mona Box
From the Botanical Garden checkpoint head back through the chappel and towards the next yellow triangle on your way and before going up you will find the Mona Box there.

Sapporo Jail – Strong Enemy
Sapporo Jail – Dire Shadow
Top left corner of this area with open streets.
Okinawa Jail – All the stuff
Mona Box and Dire Shadow are in the room just to the right of the second checkpoint. The strong enemy and the reaper can be found in the very last room of the Jail, from last checkpoint follow the path until you reach the biggest room in the middle of the map with the elevator.
Kyoto Jail – Everything
Since this Jail is weird to navigate you will have to trial and error through the portals for Dire Shadow and strong enemy. They are both in the rooms where you found the dog statues during the story. The Mona Box is in the room with 2 lamps you can jump on for a Phantom Dash.
Osaka Jail – Strong Enemy
From the Zoo checkpoint just behind the corner.
Osaka Jail – Mona Box

From the third checkpoint run straight ahead past the tower entrance to find it.
Jail of the Abyss – Mona Box
From the third checkpoint simply climb up 2 ledges to find it.
Jail of the Abyss – Dire Shadow
From the start of the Jail simply follow the main path to find it at the beginning of the Jail.
Tree of Knowledge – Strong Enemy
Final Checkpoint, just before the entrance to the final boss.
Tree of Knowledge – Dire Shadow and Mona Box
The Dire Shadow is hard to miss while navigating through the narrow hallways of this short Jail, the Mona Box will be on the 5th floor (you can see the floor numbers on the wall after screen transition) next to a chest on a ledge to your right.
