The Storm Blade myth lets you visit Jin Sakai’s old refuge and recover three keepsakes: the Storm Blade sword kit, the Clan Sakai Stag Helmet, and the Ghost Mask. The tale is available in Oshima Coast and plays out as a focused platforming, exploration, and duel sequence with minor story spoilers.

Prerequisites and spoiler note

Expect narrative callbacks and a late-game location. Oshima Coast opens after progressing the story, and the quest marker appears in the region’s far southwest. The tale includes a short chase, a duel, and a graveside interaction.

Start the Storm Blade myth (Oshima Coast, southwest)

Step 1: Reach the Oshima Coast region and ride to the extreme southwest corner. Listen for the hyōshigi clappers that announce the storyteller nearby.

Step 2: Find the Forgotten Shrine and speak to the Storyteller (Ugetsu) to begin the Storm Blade myth. This unlocks the path beyond the shrine.

Step 3: Climb the stone steps behind the storyteller to the first gate, turn right, and cut through the bamboo thickets to reveal a fox shrine. Bow to it to summon a shadow fox guide.

Follow the fox to the Glade and the Lost Shinobi’s Den

Step 1: Trail the fox through a linear platforming route marked by Sakai lamps until you reach the Glade of Remembrance. Open the chest beneath the crimson tree to read a haiku.

Step 2: Continue to the clearing with a waterfall and a dilapidated house labeled the Lost Shinobi’s Den. Enter and search the interior for relics from Jin’s life.

Step 3: Pick up the Clan Sakai Stag Helmet inside the den. This cosmetic unlocks immediately and can be equipped later from your appearance menu.

Enter the cave and attempt to claim the Storm Blade

Step 1: Climb onto the house roof, shimmy along the cliff, and enter the cave behind the waterfall. Move deeper until you reach the altar with the Storm Blade.

Step 2: Interact with the sword to trigger an ambush. A Nine Tails raider steals the blade while others stay to fight—clear the remaining enemies in the cavern.

Step 3: Exit the cave into the pool below, then follow the downstream route. Expect a collapsing bridge and a simple crossing; the fox will reappear to keep you on track.

Track the thief via the Home of the First Shinobi

Step 1: Enter the field of white flowers and explore the house dubbed the Home of the First Shinobi. Examine the workshop items to learn more about Jin’s later years.

Step 2: Inspect the muddy ground outside the house to spot footprints leading to a nearby gate. Open it to reach the burial grove.

Duel for the Storm Blade, unlock Dance of Wrath, and claim the Ghost Mask

Step 1: Duel the Nine Tails Sword Thief in the grove. Use patient parries and well-timed counters; the fight escalates when the thief flames the blade.

Step 2: After the duel, the Storm Blade sword kit is awarded and the Dance of Wrath technique unlocks. Finish off the remaining raiders in the grove.

Step 3: Approach Jin’s gravestone and bow. The Ghost Mask appears in front of you—pick it up to add the mask to your cosmetics.

Rewards and how they work

These are the permanent unlocks from the Storm Blade myth and how they function in play:

Item Type Where you get it Notes
Stag Helmet (Clan Sakai). Headgear cosmetic. Inside the Lost Shinobi’s Den. Equip via headgear appearance.
Storm Blade. Katana sword kit cosmetic. Won after the duel with the Sword Thief. Purely visual; apply in Gear > Weapons > Katana.
Dance of Wrath. Combat technique. Unlocked alongside the Storm Blade. Remains available regardless of which sword kit you equip.
Ghost Mask. Mask cosmetic. Appears when you bow at Jin’s grave. Equip in Gear > Masks.

Equip the Storm Blade kit and Ghost Mask

Step 1: Open the Gear menu, select Weapons, then Katana, and choose the Storm Blade as your sword kit. This changes the katana’s appearance without altering stats.

Step 2: In Gear, open Masks and select the Ghost Mask to wear it. Masks are cosmetic and can be swapped at any time.

Step 3: Use Dance of Wrath in combat as desired; the technique remains active after the tale concludes and does not require the Storm Blade kit to be equipped.

You’ll also spot Jin’s timeworn armor during this tale; it’s a static relic and can’t be worn. Enjoy the nods to Tsushima while you put the new technique to work.
