Go to the Ice Castle in the Second Sea
You can obtain the Rengoku sword in Blox Fruits within the Ice Castle location of the Second Sea map. Ice Castle is quite close to the Snow Mountain location. Head to the island with a large castle structure, which is quite visible from a distance.
The Ice Castle
Note that level is relevant for this finding of the hidden Rengoku sword in Blox Fruits because you’ll need to kill enemies to do it. Ice castle is a location with enemies in the 1,350-1,450 level range. Fighting the NPCs there could be tricky for players under level 1,200.
Kill NPCs to Obtain the Hidden Key
When you’ve reached the Ice Castle, you will need to obtain the Hidden Key for opening the chest that includes the Rengoku. To do this, you must kill Snow Lurkers, Arctic Warriors, or the Awakened Ice Admiral boss, from which the key randomly drops. The Hidden Key drop rate for the Ice Admiral is said to be about five percent, but it is lower for the Arctic Warriors or Snow Lurkers.
Thus, it might take a while (possibly 30 minutes to one hour or even longer) to kill enough enemies for the Hidden Key to drop. You can try defeating Ice Admiral, but you must wait for him to respawn after killing him. Focus on quickly killing many Arctic Warriors and Snow Lurkers when the Ice Admiral isn’t available. They might only have more like a one percent drop chance, but you can kill them much quicker.
The Hidden Key
When the Hidden Key drops for you, you’ll notice it in the item bar at the bottom of the screen. Press the item keyboard number to hold the Hidden Key, as shown in the snapshot below. This is your ticket for obtaining the Rengoku sword in Blox Fruits.
Unlock the Rengoku Sword Chest
Now, you’ll need to find the chest containing the Rengoku sword in Blox Fruits. To do so, walk through the door entrances for the Ice Castle to enter the room that includes the Ice Admiral. Turn right when entering that room to walk along the red carpet.
The chest containing the Rengoku
Walk along the red carpet until you reach the wall and the end of it. Turn left to walk through the wall highlighted in the snapshot directly below. There, you’ll find a chest for the Rengoku sword in Blox Fruits hidden behind that wall. Walk up the chest when holding the Hidden Key to open it and get your Rengoku!

Try Out Your New Rengoku Sword
The Rengoku will now be in your inventory. Click Menu > Item and select that weapon to equip. Then, try it out by slashing away at the Arctic Warriors and Snow Lurkers.
The Rengoku in the item inventory
The Rengoku sword in Blox Fruits looks more like a lightsaber out of Star Wars. It’s a long sword with a good range that enables you to attack enemies from some distance away. This blade has Demon Slash Slayer and Burning Slash move sets you can unlock by reaching the 150 and 350 mastery levels. Demon Slash unleashes multiple slashes, and Burning Slash launches flame attacks on enemies.
The Rengoku sword
You’ll also unlock the Samurai title after obtaining the Rengoku sword in Blox Fruits. You can change your character’s title to Sumarai at the Café in the Kingdom of Rose. Climb down the ladder from the hole in the floor behind the counter there to reach and speak to the Titles Specialist. Select “Sure” when asked to change your title, and select Sumarai by clicking the Equip option for it.
The Rengoku sword in Blox Fruits is among the better blades you can wield. Obtaining the Hidden Key for getting this sword requires some patience. However, it’s certainly worth getting this blade if you’re currently utilizing a common, rare, or uncommon sword.
