Powers & Abilities The Japanese legend behind Enma and Wado Ichimonji

In my opinion, both Enma and Wado Ichimonji are inspired by 2 fictional swords from a legend where Masamune and Muramasa are said to have met :
For those who may not know both Goro Nyudo Masamune and Sengo Muramasa were rather famous swordsmiths who were believe to have lived in 12th-13th century and 15-16th century respectively despite their capabilities they were a contrast of individuals as Masamune was regarded as very calm and controlled whereas Muramasa was seen as being aggressive and described as being violent and had an ill-balanced mind verging on the brink of madness.
Whilst it is only said In legends that these two encountered each other there is a considerable legend that details the two smiths and it goes as followed.

The legend tells of a test where Muramasa challenged his master, Masamune, to see who could make a finer sword. They both worked tirelessly and put their finest skills to work to fabricate the best blade they could. Eventually, when both swords were finished, they decided to test the results.
Since craftsmanship and aesthetics were not the only ways to decide whose weapon was superior, the men agreed to test their projects by suspending each blade over a small creek. The edges would cut anything riding along the water’s surface.

Muramasa's sword, the "Juuchi Yosamu" (meaning “10,000 Cold Nights”), managed to indiscriminately slice everything that made contact with its edge: fish, stray leaves, and even the air blowing against it were all cut effortlessly.
Highly impressed with the sharpness of his student’s weapon, Masamune lowered his sword, the "Yawarakai-Te" (meaning “Tender Hands”), into the current and waited patiently. The leaves passing over Yawarakai-Te’s edge continued their travel with the current. Fish brushing past the blade never received so much as a nick, and the wind passing across the instrument merely hissed as a gentle breeze.

After a while, Muramasa began to scoff at his master for his apparent lack of skill in the making of his sword. Masamune was smiling to himself, albeit at his student’s lack of understanding. He pulled up his sword, dried it, and sheathed it. All the while, Muramasa was heckling him for his sword's inability to cut anything.

A monk, who had been watching the whole ordeal, walked over and bowed low to the two sword masters. He then began to explain what he had seen.
"The first of the swords was by all accounts a fine sword, however it is a blood thirsty, evil blade, as it does not discriminate as to who or what it will cut. It may just as well be cutting down butterflies as severing human heads. The second was by far the finer of the two, as it does not needlessly cut anything possessed of innocence or that did not deserve to be cut."

So if the parallel is true, I think Kozaburo too may have forged Enma in a particularly aggressive and violent mindset with the will to make it slice indiscriminately anything that made contact with its edge : trees, cliffs, or even the air blowing against it. The emotions which pushed him into this state of mind must have conferred Enma a willingness to cut as deeply as possible whatever is in its path by maximizing its destructive power by sucking up its owner's Ryuo.

The same thing may have happened with Wado Ichimonji but in a different way : if Enma is the result of Kozaburo's will to indiscriminately slice everything, then Wado is the result of his will to cut nothing.
So, rather than making something ominious, he crafted a harmonious blade able to not cut anything possessed of innocence or being undeserved to be cut. Which fits with the translation of the name "Wado Ichimonji" meaning “Straight Line through the Path of Harmony”.


- Enma : sucking up its owner's Ryuo to maximize its destructive power.
- Wado : going through walls or others objects (like how Anubis's stand does in Stardust Crusaders).
