MTL - Bleach: Secret Intentions - Chapter 24 : Rangiku Matsumoto

When she was ten, she said, “When I grow up, I want to be the President!”“It's impossible, but you can be the President's wife,” he replied.He gazed at her tenderly. His youthful eyes filled with deep affection, as if he wanted to give her the whole world.When she was thirty-three, due to a leak of military secrets, she was imprisoned for treason, and she saw his signature on the death sentence document.She finally understood that the so-called undying love was fake, and that power and status were the true goals.Love is just like a ghost—more talked about than seen....Reborn and back to the age of twenty, she opened her eyes and shouted, “I must be the President!”“But, Madam... Your husband is already the President,” someone said.She was stunned for only a second, then viciously replied, “Then I'll take him down first, and I'll become the President!”A man gently pushed open the half-closed door, chuckling softly, “Did I hear wrong? Sweetie, you want to... take me down?”

After his fall, the Duke who was distant with his wife and daughter recalled his memories of another world. With a new perspective on life, he swore to cherish and protect those two.

A polite and lethargic boy was reincarnated in another world as a vampire bishoujo.

In this world, orphans or just anyone without any hope for this world can apply to become a “walking target”. Their sole purpose is to be a practicing dummy for the students of the sect who train to become “Demon Hunters”. These students need “walking targets” to test their training on living, walking beings of flesh and blood.
In exchange, they will be provided with food & shelter.
Their existence value is lower than a slave, but if they manage to survive a few years they can receive a life long pension.

Xiao Han is such a “walking target”. One time he witnessed a powerful Demon Hunter disposing a demon. When the demon died, a fragment of the demon that managed to escape entered Xiao Han’s heart. No one saw that, and even Xiao Han himself only felt some discomfort for an instant.

But that thing in his heart soon gave Xiao Han visions, and the first one is of a cultivation method which allows Xiao Han to absorb damage to enhance his body. A perfect cultivation method for a “walking target”.
