Enma

Placed within the twenty-one Great Grade swords, Enma emerged from the workshop of the storied smith Shimotsuki Kouzaburou, who considered it the crowning achievement of his career, superior even to Wado Ichimonji. Ownership traveled from Kouzuki Oden down to his daughter Kouzuki Hiyori, and finally to Roronoa Zoro, who wields it today among his trio of blades. Sukiyaki once said the sword could slice all the way down into the depths of hell, a deliberate counterpart to its sibling Ame no Habakiri, described as capable of cleaving the heavens.

As its Volume 96 cover art reveals, the katana bends in a moderate curve and wears a colour scheme of lilac and gold. A trefoil guard mirrors the one on Ame no Habakiri, while both the lacquered grip and the scabbard bear plain five-petalled floral motifs, and along the edge runs a jagged, flame-shaped temper line. Its notorious quirk is that the blade draws out an excess of the user's Armament Haki, hardening the steel and biting deeper than the swordsman ever meant. That trait earned it a reputation as a weapon nobody could subdue: before Zoro, Oden alone had bent it to his will, and Kin'emon, who led the Scabbards, was afraid of the thing. Testing it for the first time, Zoro shaved off part of a cliff while aiming merely to cut down a tree, and the sword left his right arm withered before his Haki skill let him reclaim the drained power, a recovery Sukiyaki praised since ordinary fighters would have been reduced to empty shells.

In Oden's hands the katana achieved legendary feats, aiding in the bisection of the giant Mountain God and enduring exchanges with the Supreme Grade blades of Edward Newgate and Gol D. Roger. Alongside Ame no Habakiri it dealt Kaidou the only scar he ever bore, making the pair the sole weapons known to wound that Emperor. After Oden died the swords passed to his wife Toki and were later kept safe by his father Sukiyaki, until Hiyori offered Enma to Zoro as a fair trade for the national treasure Shusui, which he had earned from its undead former holder. Amid the assault on Onigashima the blade began giving off Oden's own aura like a flame, unnerving Big Mom and leading Kaidou to identify it as his old rival's sword. Zoro reopened Kaidou's scar and later cut down a Lunarian with it. Should he ever fix the weapon into a permanent black blade, Sukiyaki believes its ranking might climb toward Supreme Grade.
