Sword of Rupture
The Sword of Rupture has an abnormal shape that doesn't match what would normally be classified as something specialized like a sword. While it has a grip, handguard, and is the same length as a longsword, the section that should contain a blade deviates from the normal form of an edged weapon. The "blade" itself and the tip of the sword, spun in a spiral shape, are dull. It has the shape of a cylindrical, drill-shaped pillar made up of three independently rotating segments engraved with crimson cuneiform lettering that spin slowly in alternating direction like querns, the middle segment spinning clockwise and the top and bottom segments spinning counterclockwise. Its overall design is modeled after a bedrock drill used to dig undersea tunnels that looks as if were crossed with a spear. It has been given multiple gears to dig a gigantic hole as if the three separately spinning parts were eating at the bedrock little by little.
The Kairi Ken can be used as a close combat weapon wielded much like a regular sword, and even with its dull tip, it is able to pierce directly through someone’s chest and slowly grind at their vitals inside. It combines the basic principles of the Kanonho and a Kyōmeisen upon activation, the triblade segments gradually begin to rotate faster with each revolution, acting in concert with the movement of the Heavens. As they begin rotating rapidly, each creaking with weight and power equivalent to tectonic movement, they create a shrilling howl as like with a Kyōmeisen the Acoustium that makes up the blade absorbs the sound waves caused by the rotations. This creates potential energy as the Kairi Ken begins to swallow, compress, and accelerate wind pressure into a storm of wind and light
