Dark Magic - Yami uses this form of magic to generate and manipulate the power of darkness.

1) Dark Cloaked Lightless Slash

Yami channels darkness into his sword and releases that darkness with a slash that flies at the opponent. The wave of darkness retains the same sharpness as an edged weapon and also has the ability to absorb Light Magic.

2) Black Hole

Yami creates a small black hole which draws in and absorbs other spells. However, the hole's size is limited to about five meters.

3) Dark Cloaked Dimenson Slash

Yami channels darkness into his sword and, with a downward slash, releases that darkness which flies at the opponent. The slash is able to cut through Spatial Magic and large clouds of mana.

4) Dark Cloaked Dimension Slash Equinox

After taking control of the surrounding mana, Yami performs a Dark Cloaked Dimension Slash, greatly extending the range and reach.

5) Black Moon

Yami takes control of the surrounding mana and then creates a Black Hole overhead, expanding the range of its absorption over a defined area.
Yami is also able to discriminate what gets absorbed by the spell, such as erasing an opponent's spell while leaving an ally's spell unaffected.

6) Dark Cloaked Iai Slash

Yami sheathes his sword, condenses the area of Black Moon's effect, and waits for his opponent to attack. Once the opponent is in range, Yami quickly draws the blade, and dashes forward, slashing the opponent.
