Shibuya Jail – Strong Enemy
In the middle of the very first area of this Jail.
Shibuya Jail – Gouma
In the street between the tower and the checkpoint on the left of the map.
Shibuya Jail – Mona Box
In the area on the very left where the chest is.
Sendai Jail – Strong Enemy
In the open area just south of the checkpoint.
Sendai Jail – Gouma
You actually saw him during the story, during the sequence with your first treasure demon. He will be past the small chappel, just norheast of the checkpoint.
Sendai Jail – Mona Box
On the roofs in the top left corner of this map. You will need to climb the roof next to the checkpoint and continue traversing the roof via the invisible platforms, at the top left drop to the lower roof for the box.
Sapporo Jail – Strong Enemy + 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. For the strong enemy instead of goign back from the checkpoint, use the snowboard to slide downhill and just before the tower the enemy will wait.
Sapporo Jail – Gouma
Top left corner of this area with open streets.
Okinawa Jail – All the stuff
Mona Box and Gouma 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 Gouma 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 Move.
Osaka Jail – Strong Enemy
From the Zoo checkpoint just behind the corner.
Osaka Jail – Mona Box
In the middle of the cargo container area. You will need to use your Third Eye to see vantage points which will take you to the Box and a Chest.
Osaka Jail – Gouma
From the third checkpoint run straight ahead past the tower entrance to find it.
Abyss Jail – Mona Box
From the third checkpoint simply climb up 2 ledges to find it.
Abyss Jail – Gouma
From the start of the Jail simply follow the main path to find it at the beginning of the Jail.
Tree of Life – Strong Enemy
Final Checkpoint, just before the entrance to the final boss.
Tree of Life – Gouma and Mona Box
The Gouma will hard to be overseen 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.
