One Piece Odyssey is Bandai Namco’s most recent open-world JRPG (Japanese Role-Playing Game) based on the anime.

Players have been awestruck by the gorgeous adaptation and the large cast of characters they encounter in the game. Of course, diverse, powerful bosses and the uniqueness of each encounter add to the excitement.

One example is the battle against Kaku in the Tower of Law’s Underground Passage. In Chapter 4, you will need to find a Gate Key to get to where Kaku currently is.

This guide will show you the location of the Gate Key and how to get to it.

After you beat Rear Admiral Barricade, you will be given the First Key. He will accidentally give away the locations of the other Two Keys.

If you follow the sign, you’ll find the other two keys. You can find the Second Key in the Service Room.

The Second Key can be found in the area shown in the photo above.

The Third Key can be a little bit tricky to find. Instead of the Vice Admiral, you’ll find the Key when you talk to this dog shown above.

Once you have all the Keys, head back to the gate and get ready to fight Kaku.

That’s all you need to do to get the Gate Key. We hope this guide helped you out.
