Finally, I have found every single item in Adventure Bar Story. The last item I found is Jormungand - Secret Catalog Equipment 25. I totally missed it when I went to the zone ??? previously. The first time I went there, I found a secret path near the exit, and assumed that's the only secret path in this zone. Why did I do that?
Thanks to Misto Soup. It made things so much easier looking for a hidden path in a mini maze.
Here's a picture of part of the zone ???.

There are some more secret paths in this game. I will keep them coming. :D Have fun!
