Which Anime Use The Heart As A Central Plot Device?

Just because I ate one chicken leg more than my brother, my father kicked me out of the house in the middle of a snowstorm. Later on, my father of an archeologist dug up my body. Due to my missing head, he did not recognize me. Even when he saw that the body had the same scars as I did, he did not care. Later on, my mother dug out my heart and showed it to her students. "Today, we will study the heart of someone with congenital heart disease." She once said she would recognize me no matter what I looked like. Mom, now that the only thing left of me is my heart, do you still recognize me?

When the nurse pulled the IV needle out of the back of my hand, her gaze was filled with pity. “Mr. Young, the heart meant for your transplant was transferred at the last minute. It was sent to the VIP ward on the seventh floor. It’s a shame, but all your pre-operation prep has gone to waste.” Marcus Stewart was warded on the seventh floor. He was the frail young man my sister brought home. Ten minutes ago, Marcus suddenly had terrible chest pain. My usually strong mother burst into tears. My stoic father slammed the table in front of every expert in the hospital, then decided to give Marcus the heart I had been waiting three years for. It was supposed to save my life. I hurried to the end of the corridor, but the green operating light had already come on. Clutching the twisting pain in my chest, I leaned against the ice-cold wall and slid to the floor. There was no need to wait anymore. My heart failure was terminal. The doctor said I would not last the next few days. The mechanical voice sounded in my head. [Master, your vital signs are rapidly deteriorating. If you terminate this body and leave this world now, you still have a chance at a new life. Would you like to proceed?] I looked at the faint grey hue of death tinging my fingertips. “...Yes.”

Many years ago, dragons discovered the supreme good that the Earth could offer to any of its creatures. A red gem, which the king of dragons named "The Heart of Magic" because of its shape, resembled a heart. The magic gem fulfilled their greatest desires. All the dragons in the world obtained a necklace with a small piece of the red gem that shone. All the dragons born afterward also carried the same necklace. Then, when the gem got stolen, this light went out of every necklace, and the dragons lost these magical abilities that the gem had given them. But before this could happen, after fulfilling these desires, the dragons used them against the humans, enslaving them, but when the gem got stolen, it was all over. Dragons are still looking for it, and humans wish never to be found so that they do not go through the same thing again. Princess Edith, after a family tragedy, she will be forced to go in search of the gem. Through the journey of investigation, she will discover that she possesses special powers that she did not know that she has until that moment. Drake is the Dragon King's son and will be secretly sent to help Edith seek the gem. Carrying his dark and heavy past on his back, he moves forward with his life with no regrets about his actions back then. Everything is about to change.

To save his childhood sweetheart, who had a congenital heart condition, my husband tricked me into signing an organ donation agreement. Then he got into a truck and ran me over right in front of the hospital. Barely clinging to life, Elliot Carter tore my heart from my chest. When my body was wheeled out of the operating room, Alan Yates came crashing to my side like a man gone mad. Seeing the gaping hole where my heart used to be, he screamed and wept: "I'm sorry… I was too late… If there's another life, I'll never let you suffer like this again…" Tears fell exactly where my heart had been, and somehow, I even felt a flicker of warmth. He spun around and ran back into the operating room. When he came out again, Elliot and Jessica Foster were lying in a pool of blood. Alan, meanwhile, had slashed his own wrist to die with me. On his deathbed, he ordered that we be buried together. Then I opened my eyes. I had been reborn. Before me stood Elliot, dressed in a wedding gown, holding a bouquet, and proposing. I flung the flowers in his face and turned to embrace Alan in the crowd. However, only a year and a half into our marriage, he changed. Alan began openly pairing up with Jessica, letting her move into our home. Worse, he claimed that our cat's mating season had disturbed Jessica's sleep, and so he allowed her to run over the cat I had raised for seven years. I could not believe it. This was not the man who had loved me so deeply in my previous life. My eyes blazing, I demanded, "What's wrong with you?" However, Alan's gaze was icy. "Nothing. I just don't love you anymore."
