The SoulTaker: Tamashii-gari (Dub)

Kyousuke Date comes home one night and finds his mother dying in a pool of her own blood. In her final moments, she stabs him in the chest. After a swift recovery, Kyousuke searches for answers regarding his mother's motives, but finds more than he bargained for when he is attacked by two rival organizations: the Hospital and the Kirihara Group. Kyousuke is surprised to discover that he has a twin sister named Runa, and both groups try to coerce information out of him about her despite his ignorance to her existence. As their assault continues, Kyousuke soon makes another discovery—he has the ability to transform into a terrifying mutant called SoulTaker. With these newfound powers, Kyousuke resolves to crush both organizations, uncover the truth behind his mother's actions, and protect Runa. After the human colony on the moon was destroyed by disease, Kyosuke Date and his mother flee to Earth- separated from their family. They take refuge in a cathedral where his mother hides as a nun for reasons unknown to Kyosuke. After dangerous people find their sanctuary, his mother stabs him before she herself is murdered.
