You can find the Rengoku Sword in the Second Sea Ice Castle. However, you cannot just pick it up and start using it. The blade is locked in a chest. You need to get the hidden key from the chest and once you have it you can unlock it. You can find this chest behind the wall on the right side of the stairs inside the main castle. This is also where you fight the Ice Admiral.
How to get the hidden key

If you don’t have the hidden key, there are two ways to get it. The best method is to kill Ice Admiral Awkaned inside the castle. Has up to a 15% chance of dropping the key when killed. However, killing the Admiral is difficult, especially if you are of a lower level. This is where the second method comes in: kill the NPCs on the island.

The NPCs that drop the key are the Snow Lurkers and the Arctic Warriors, and you can find them outside of the castle in the main island area. They have up to a 1% chance to drop the Hidden Key, which is extremely low, but killing 15-30 of them should give you the same 15% chance as the Admiral. Still, you’ll have better luck with Admiral because the game works that way. If your level is low or you’re having bad luck with the Admiral, NPCs are a great way to get the key.
