Black Hole

Black Hole(ブラックホール, Burakkuhoru)

About
After preforming the attack Supernova, the gravitational collapse of the remnants continues to occur, resulting in a gravitational field with such an incredibly high density that even light cannot escape. This phenomenon is referred to as a Black Hole. The attack itself absorbs anything present within the surrounding area, trapping it inside forever with no possibility to return.
