In Nioh 3, “The Guardian’s Box” is a side quest found in the Heian region. It’s a little different from most quests, which you start by simply talking to a character marked on the map. This guide provides a complete walkthrough of the quest, including all the rewards you’ll receive in Nioh 3.
How to Start Guardian’s Box Myth in Nioh 3

To begin this quest, travel south on the map. Within the Hachijo region, you’ll find one of the barriers you need to purify as part of the main story. Explore Rajomon, defeat all the enemies there, and then beat the boss to complete this section of the quest.
After completing that step, travel quickly to Rajomon: Suzaku Avenue. From there, run north. You’ll encounter a Wheelmonk along the way – you can fight it if you like. Continue onward, and you’ll find an Onmyo mage who needs assistance. Speak with him, and he’ll tell you that some warriors stole a box of his.
Where to Find the Box in Nioh 3
After starting the quest, go west until you find a glowing Spirit Vein. Follow it to the other side, then enter the building and touch the red Bloody Grave to begin a battle with the Demon Slayer.
Using Ochoko Cups to call in another player before the battle can help make this fight, and the one that follows, easier.
Now that you’ve beaten the Demon Slayer, open the chest to talk to Kurama Tengu. After your conversation, a mage will appear, and you’ll need to fight a Ninja Yoki and a One-eyed Oni. Once you defeat them both, you’ll finish the quest and receive Ninja’s Locks and the Smithing Text for Brave Demon Hunter’s Armor.
