Hey fellow Travelers! If you've found yourself staring at the "Activate the mechanism" objective in the Relics of Seirai quest and hearing nothing but the wind, don't worry — you're not alone. I remember exactly how this step drove me up the wall back when Genshin Impact's 2.1 version dropped, and even now in 2026, new adventurers setting foot on Seirai Island still scratch their heads over it. So grab a cup of your favorite tea (not the suspicious Chubby variety!) and let me walk you through this elegant puzzle step by step.
Relics of Seirai is one of those story quests that keeps you coming back to Inazuma's stormy shores. It dropped alongside Watatsumi Island and the almighty Raiden Shogun, and from day one it's been a fan favourite — partly for the juicy rewards: 50 Primogems, 3 Hero's Wit, and 30,000 Mora. Oh, and a sneaky hidden achievement that pops up when you least expect it. But forget the loot for a second; the real gem here is cracking the code and watching the island reveal its secrets.
Step 1: Find Fujiwara Toshiko and the Start lever
You'll meet Fujiwara Toshiko near a small, slightly creepy house on Seirai Island. After a brief chat, you'll get the famous objective. Look right beside her — there's an old wooden lever just begging to be pulled. Don't overthink it. Just walk up and yank that thing down.
Step 2: Light up the three platforms
Once the lever is down, it's showtime. Three glowing platforms will materialise nearby, each marked with a different traditional Japanese symbol. You might see a lightning bolt, a stylised flower, or a crescent moon — the exact designs can shift a bit depending on your world state, but they're impossible to miss. Your only job now is to step on each and every one of them until they're all brightly lit. There's no complicated order; run, glide, or Lumine-sprint onto them however you like. You'll hear a satisfying click with every activation, and when the third one lights up, a deep, rumbling crash shatters the silence.
Right on cue, Fujiwara Toshiko will enter full panic mode:
Fujiwara Toshiko: "Wh—What was that noise... Did you just see that? A giant... hole just opened up over there!"
Fujiwara Toshiko: "Looks like there's... some sort of basement here! Let's go in and have a look, come on!"
And she's absolutely right — on the right side of her house, the earth has yawned open into a huge pit. That's your entrance.
What happens next?
Jump (or carefully glide) down into the darkness and you'll land in a sprawling underground chamber. But hold onto your glider, because you've just triggered the next stage of the quest, and it's a notch more complex than what you just did. Down there, you might face relay stone puzzles, pressure plates, or electro-construct mechanics — it varies a bit from player to player. Getting the above-ground mechanism activated was the gate, and now you're in for the real brain-teaser. I'll have a separate deep-dive for that basement puzzle, but trust me, once you've made it this far, you're already halfway to the primogem glory.
A few handy tips before you go
-
💡 If the glowing platforms are hard to see, set your in-game clock to noon. Harsh Seirai storms can wash out the effects.
-
💡 Use a character like Kazuha or Venti to create an updraft if you want a bird's-eye view of the platform layout.
-
💡 Make sure your graphics settings aren't on the lowest level — the activation glow can become near invisible on potato mode.
-
💡 This is a single-player-only sequence, so take your time and soak in the atmosphere. The music down here is hauntingly beautiful.
Rewards breakdown
Here's what you'll walk away with once the entire Relics of Seirai chain is complete:

| Hero's Wit | 3 |

So there you have it — pull the lever, light the platforms, and follow Fujiwara into the abyss. Not so mind-bending once you know the trick, right? Whether you're a launch-day veteran or a fresh Traveler exploring Inazuma in 2026, this little puzzle is a great reminder that sometimes the simplest solutions are the most satisfying. Happy adventuring, and may the gacha gods bless your next ten-pull!
