Where to find Corneo's Secret Stashes in Final Fantasy VII Remake
In Chapter 14 of the main story, talk to the journalist outside of the Sector 5 Slums' north entrance. You'll get a side quest called 'Corneo's Secret Stash'.
First, check the Guardian Angel's hideout at Lookout Point, north-east of the Sector 5 Slums. There you'll find Mireille, who'll tell you to find Kyrie, the girl with the hat and striped stockings from the slums. Make your way to the Church at the very north of the map. You'll find Kyrie inside next to Aerith's flower patch.
You'll then be tasked with winning a special match in Corneo's Colosseum in Wall Market. Head over, win the fight, and then go back to Kyrie. You'll get the key to Corneo's secret stashes.
Now you just have to find them...
Corneo's biggest secret stash is located at Steel Mountain. Be sure to smash every crate and loot every container -- there are quite a few of them.
The exact location of the first stash is here, where the player arrow is:
Corneo's second secret stash is located in the Collapsed Expressway. Use the northern entrance to get in (the one that connects to the S6-5 road). It's the first room on the left.
Unfortunately, there isn't much in this one -- just a few crates that you can break and a chest.
Corneo's final secret stash can only be accessed once you progress further into Chapter 14. When you're back in the sewers as part of the story, and the water is drained, retrace your steps and you'll be able to find the final locked door.
This final stash is another big one, but it's guarded by a tough enemy. Make sure to break all the crates and loot the multiple chests dotted about once you're finished fighting.
Once you've looted every stash, simply head back to Marle outside of Sector 7 to complete the side quest once and for all.
