Dark Night Slash (ダーク・ナイト・スラッシュDāku naito surasshu) is a second deadly attack along with Black Edge Throw and Dark Night Storm and was used for fighting against his enemies. If the battle with Death Rebel continues for a long period of time, he'll spins and powered up his Deatheria and launches a giant crescent waves at the enemies.
The Dark Night Slash is act like the Meidō Zangetsuha which launches five or more giant crescent waves from Death Rebel's Deatheria, which cover the entire area in front of him. Whenever hit something, it creates a massive black circle explosion that will send an entire body directly into Hell, leaving no trace left behind. However, when one is first used due to Ikuto's dark magic, which is very powerful enough to destroy a half of the city.
Also the Dark Night Slash as Finishing Move which used against the enemy Mamodo is weakened from fighting with Death Rebel. Afterwards it creates a massive black circle explosion that sends the Artificial Book Keepers when weakened into space.
- In Shugo Chara Crossover, he first used to break and destroy Platinum Royale's Holy Crown Special. Hits not only The Guardians, but also destroys a half of the city as well, sending them directly into space, leaving no trace left behind, but they survived out from massive black circle explosion.
- Second used against Amu Amulet Heart in battle (which Amu manages to dodge).
- Third used against a legion of enemy Mamodos and Artificial Book Keepers in battle. Annihilating them.
- In terms of appearance of the Dark Night Slash is much the same as Meidō Zangetsuha which shared the fashion as from the anime Inuyasha: The Final Act.
