The SoulTaker - S01

One night, Kyousuke Date returns home to find his mother bleeding to death. With her dying breath, she stabs him in the chest. Though he recovers quickly, Kyousuke sets out to understand why she attacked him-only to be caught in a violent struggle between two factions: the Hospital and the Kirihara Group. To his shock, he learns he has a twin sister named Runa, and both groups aggressively demand information about her-even though he never knew she existed. As the attacks escalate, Kyousuke realizes he can transform into a monstrous mutant known as SoulTaker. With this power, he vows to destroy both organizations, unravel the mystery of his mother’s final act, and shield Runa from harm.
