Okuchiの実 — 神話悪魔の実

Okuchi is a Mythical-class Devil Fruit with extreme burst damage and crowd control. Its global animation overhaul and fully animated Awakened Beast Form make it one of the most visually distinct fruits in the current meta. Full passive lists and database skill tags live on the Okuchi detail page.

入手方法

データベース注記： Okuchi is listed under the Mythical tier with competitive placement pending — check the fruit page for live balance updates.

基本形態スキル

覚醒獣形態（Eキー）

Activate Awakened Beast Form to enter the Zoan transformation. Hitbox scaling, AoE radius, and visual effects all increase. スキルs upgrade as follows:

Pair Okuchi with Observation Haki training and tank accessories from the Accessories Database if you plan to main it in PvP.

シービースト装備 V2（ヘルメット＆アーマー）

Sea Beast Helmet V2 and Sea Beast Armor V2 are among the strongest stat accessories in the current patch. Both are crafted through Doran the Forge (the Third Sea Blacksmith NPC) and share the same core material: the Seabeast Heart.

シービーストハート — 核心素材

Bonus drops from the same encounter:

Use the World Map to plan sailing routes across Sea 2 and Sea 3 grid sectors before committing to a long farm session.

Doran the Forgeでのクラフト

Visit Doran the Forge on the Third Sea starter island. Each V2 piece requires 2× Seabeast Heart.

The helmet's bonus Observation dodge stacks with your Observation Haki cap — a major PvP advantage. Crafting both pieces is a top priority for any tank or bruiser build heading into Third Sea content.

フィッシュマン格闘スタイル V2

Fishman Fighting Style V2 upgrades Fishman Karate into a water-themed moveset with superior range and AoE. This is separate from the Fishborne race V2 upgrade covered in the Third Sea Update Guide — here we focus on the fighting style unlock.

必要条件

Budget your Seabeast Heart carefully: you need 4 hearts total if you are crafting both armor pieces and unlocking Fishman V2 in the same push (2 for helmet, 2 for armor, plus 2 for the style — 6 hearts if doing everything at once).

ファームのコツ

• Prioritize party farming — Seabeast Heart is shared between accessory crafting and Fishman V2, so group up for Sea Beast (Sea 2 & 3) runs to cut grind time.
• Helmet before armor or style — the Sea Beast Helmet V2 Observation dodge bonus pays off immediately in PvP.
• Track your material math — open the Materials Database to confirm drop rates before you sink hours into open-water sailing.
• Stack with race passives — pairing Fishman Fighting Style V2 with Fishborne water utility creates one of the strongest aquatic builds in the current meta.

Seabeast Heart is the bottleneck for every path in this guide. Farm Angry Sea Beast encounters first, craft your V2 armor at Doran the Forge, then take the leftover hearts to Sage Of Combat for Fishman Fighting Style V2. With Okuchi in your fruit slot and both V2 accessories equipped, you will have one of the most complete Third Sea loadouts available.
