Kettetsu is a yokai in Dandadan, once human, whose spiritual power was stripped away by Saint-Germain and handed to one of Red Baron's agents. Manifesting as an iron bull, its essence is delivered through a kozuka knife.
Kettetsu stands roughly two meters tall as an upright bull, its muscular humanoid frame forged of iron. Its eyes are formed of concentric circles, and the only clothing it wears is a pair of briefs.
The full nature of Kettetsu's spiritual power has never been spelled out. What is known comes from the agent who received it through a kozuka knife holding the yokai's essence: the power appears to express itself as an iron physique that grows tougher the more it is struck.
Kettetsu's name traces to a mythical beast cited in the Shenyi Jing, the Book of Gods and Strange Things, described as resembling a water buffalo with jet-dark fur that fed on iron and drank water, with people said to forge steel-hard weapons from its dung. Within the series its form, channeled through the Power User, is depicted in the Kozuka Knives Arc. Its profile in Volume 21 hints at inspiration from the Chicago Bulls, noting that its briefs were made by a Chicago undergarment company. A drawing error in Chapter 178 gave the Power User's Kettetsu form human feet, a slip that went uncorrected in the volume release.

The transformation everyone knows, the follow-up question nobody would touch. Why we made a smooth R&B track about the golden glow Dragon Ball never talks about....

Five Bleach female characters, ranked and settled. Yoruichi sits at number five, the spot nobody expects, and our number one is an Arrancar with a soft heart....
