Notes

Kuro's Breathing of Curses (Curses will automatically start to decompose whatever is around them) (Forms 10+ Require A Curse To Flow Within The User's Body)
Nichirin Type: Dual Wielding Perfect Blades (Levi's From Freedom Awaits(That Shit Is Like Five Feet Long))

First Form: Curse Sway (Kuro's body starts to sway, random curses from the dead orbiting around the user. The curses will slowly decompose whatever they touch except the user. (This applies to allies too)

Second Form: Crushing Curses (Kuro jumps in the air with their Nichirins aimed down, slamming down on a target of their choice. On impact of anything, curses swarm the area and rise into the air.)

Third Form: Curse Command (Point the Nichirins forward, curses lunging in front of them from behind the user)

Fourth Form: Ginkui Lock (Throw one of the Nichirins, if it hits an enemy it sticks inside and unleashes curses inside of them (This holds them in place). If the second sword is thrown and makes impact, both swords explode into curses and reform in the user's hand.)

Fifth Form: Corrosion Curses (Stab both Nichirins into the ground. Curses will flow under everything within a half a mile radius, shaking and possible breaking any ground)

Sixth Form: Corrupting Cursed Clock (Summon a bunch of curses to form a clock with 15 seconds to midnight. Once the clock strikes midnight, every single curse grows twice in size, and twice in strength. They run on a rampage for around 15 seconds while under Kuro's Command.)

"Let's End This With A Bang,"
Kuro's Cursed Dawn; Form Seven; Kamikaze Curse (Dash up to the target, appearing behind them. Ginkui lock instantly activates to both people, target and Kuro. Kuro stabs the target with both swords, stabbing himself in the process. The swords create a connected flow of curses between the two, making the curses run at a molecular level. Within 30 seconds, Kuro can share some final words with the target. After the 30 seconds is up, Kuro and the Target explode within a one mile radius of curses.
