If you want to find all the secret areas in One Punch Man Destiny/A Hero’s Destiny, this guide will help you out big time.
The first secret area is located near the abnormal. You will need to fly up to that location.
Go to the little corner in the grass area. Jump in it, and you’ll find the first Secret Area.
You may find two clothes here. If you want to leave the area, step onto the red button.
The second area is located very close to the Boros NPC quest.
Just go through the small hole area, and you’ll find a big shop area. It comes with a lot of cool clothes.
They all look pretty good. Anyways, that’s it for these instructions.
