She hires him to protect her "until death do us part", and thus begins a long road of action-packed confrontations to keep the young girl safe and her abilities out of the hands of those who would exploit them.

Haruka Tōyama, a young girl, is kidnapped by agents of a company named Ex-Solid due to her precognition abilities.

She quickly finds sanctuary with a man named Hijikata Mamoru, a blind swordsman, ex-kendoka, and convict who is proficient in the use of a katana, and desperately runs him down in the street.

Needing a bit more help, contact is made with their parent company, a secret and elite vigilante paramilitary group called the Element Network.

Until Death Do Us Part has been published in Japan with 24 volumes by Square Enix[5] after it was initially serialized on Young Gangan's December 2005 issue.
