Light Raids in Sailor Piece are found on Blue Planet Island in Sea 2 — unlock the second sea, bring a Raid Key, and talk to the Raid Portal NPC to pick “Light Raid” and start a run.
Everything happens on a single raid-hub island, Sea 2 of Sailor Piece, and the run itself is short to set up once you know the two things you actually need: access to the second sea and a key to open the portal. Below is exactly where the raid lives, the on-screen steps to start one, where keys come from, and what the clears are really for.
Where Light Raids are and what you need first
Light Raids are tucked away on Blue Planet Island in Sea 2 (C2), and they’re the only place this content shows up — there is no Sea 1 version. The raid gamemode sits on this island, run through a Raid Portal NPC near the center of the map, so reaching it at all means you’ve already cleared the gate into the second sea.
There are two hard prerequisites and not much else. First, you need Sea 2 / C2 access; second, you need at least one Raid Key, because every run consumes one to open the portal. Worth knowing: the sources don’t point to any fixed level requirement to enter a Light Raid — only the Sea 2 unlock is confirmed — though you’ll want a real build before you fight (more on that below).
How to start a Light Raid in Sailor Piece
STEP 1/6
Unlock Sea 2 (C2)
Raid content only appears once you’ve reached the second sea — the actual route to C2 isn’t shown here, so sort that progression first.
STEP 2/6
Sail to Blue Planet Island
This Sea 2 island is the dedicated raid hub (some guides call it Blue Island — same place).
STEP 3/6
Talk to the Raid NPC
Find the raid portal NPC on the island and interact with it to open the raid selection menu.
STEP 4/6
Select Light Raid and start it
Choose the Light Raid option from the menu; opening the portal spends one Raid Key.
STEP 5/6
Pick your difficulty
You can run easy, medium, or hard, so match it to your build and damage.
STEP 6/6
Defeat the bosses
Clear the raid’s bosses to finish the run and collect the drops.

Farming Raid Keys in Sea 2
Since every run burns a key, the most common way to get stuck is arriving at the portal with nothing to open it. Raid Keys drop from NPCs in Sea 2, specifically the fist/combat enemies you’ll already be fighting out there, so farming them is mostly a matter of grinding C2 mobs.
For named targets, a couple of options have been reported: Fast Ninjas on Punch Island and Spirit Fighters on Blue Planet. Treat those as leads rather than the only routes — they come from a single source — but the general rule (Sea 2 combat NPCs drop keys) is consistent across guides.
Farm at least one Raid Key in Sea 2 before you sail to Blue Planet — the Raid Portal won’t open without one, and it’s the single most common reason players get turned away.
Light Raid rewards and the Light V2 payoff
| Upgrade | Base requirement | Light Fragments | Gem cost (unverified) |
|---|---|---|---|
| Light V2 | Light Fruit | 5 | 1,000,000 vs 1,000,000,000 (disputed) |
| F move (+30% damage) | Bearer of Light title | 25 | ~2,500,000,000 (single source) |
The headline drop is Light Fragments, which are reportedly a 100% drop per clear and come only from this raid — that’s the real reason to grind it. A full run also drops a light outfit and a mirror of light, but Fragments are what feed the upgrade path everyone’s actually here for.
Those Fragments go toward Light V2, the awakened form of the Light Fruit. The build agrees on the Fruit and the 5 Light Fragments, but the gem cost is genuinely disputed: some guides list 1,000,000 Gems while another says 1,000,000,000 (1 billion) Gems. That’s a real conflict and isn’t officially confirmed, so plan loosely until you can check it in-game. The Light V2 trainer NPC reportedly stands right beside the Raid Portal NPC on the same island. Beyond V2, an additional 25 Light Fragments plus the Bearer of Light title unlock the F move and a +30% damage bonus — one source also attaches a 2.5 billion Gem cost to it, but that’s single-source and unverified. The title itself is said to drop at roughly 0.67%–1.21% with a 125 pity, again from one source.
Mistakes that keep players out of Light Raids
The big one is searching Sea 1 — this content simply isn’t there, and the Blue Planet / Blue Island name swap sends people looking for an island that doesn’t exist as a separate place. The other classic is sailing all the way to the hub with no Raid Key and getting stuck at the portal.
Frequently Asked Questions
Where are Light Raids located in Sailor Piece?
On Blue Planet Island in Sea 2 (C2), run through the Raid Portal NPC near the center of the island. Some guides call it Blue Island, but it’s the same Sea 2 raid hub.
Can you do Light Raids in Sea 1?
No. Light Raids are Sea 2-only content — if you’re still in the first sea, there’s nothing to find. You need to unlock C2 first.
Do you need a Raid Key, and where do you get one?
Yes — each run consumes one Raid Key. Keys drop from Sea 2 combat NPCs; reported targets include Fast Ninjas on Punch Island and Spirit Fighters on Blue Planet, though those specific spots come from a single source.
What do Light Raids drop?
A clear drops Light Fragments (reportedly guaranteed every run), plus a light outfit and a mirror of light. Light Fragments are the main draw because they feed the Light V2 upgrade.
How many Light Fragments do you need for Light V2 and the F move?
5 Light Fragments for Light V2 (alongside the Light Fruit and a disputed gem cost), and an additional 25 Light Fragments plus the Bearer of Light title for the F move and its +30% damage bonus.
