Kach is special, one of few people in the world with rare blood the color of Sapphire which can grant them unimaginable power. These people usually sell their blood for money on the black market, mostly because if the government knew they existed, they would exploit them for their blood and would soon be extinct as part of the human race. Kach has a bad run-in on a deal and ends up almost dying when the grim reaper himself actually does the opposite of his job description and helps the poor mortal. Kach damn near falls in love instantly with a nurse met at the hospital but Kach is worried someone else will come and finish the job and their affections for her will endanger her life.
