How Does Sanemi Shinazugawa Die In Demon Slayer?

Having an Awakenist as my wife meant enduring her monkish attitude toward sex. We could only be intimate on the sixteenth of every month. Every detail—my position, rhythm, even my expression—had to follow her rigid rules. If I showed too much pleasure, she would immediately rise and leave. We had been married for five years. Was I ever tired of this? Yes. Still, I always gave in. I accepted these limitations because I loved her. "The Saintess loves me too," I told myself. That faith shattered the day I was sent to extinguish a hotel fire. Amid the flames, I found my wife pressed close to a man in disheveled clothes. Between their arms was a young boy.

300 years ago, humankind created their own nightmare. Demons, are originally humans but the lust for power changed them inadequately, this is humans own doing. Around 300 years ago, a large asteroid bombarded the earth's very ground. This is the beginning of the birth of demons. This meteor was large, but out of the blue, a mysterious lifeform is intact in it's very core. A human named Cruzius Akiyoma was intrigued when witnessing these menacing looking creature. He interpret this as a blessing from heaven. He then owned the creature and conducted an experiment. He was surprised when he saw the structure and building blocks of life of this creature. He obsessedly pictured this as a one stepping stone through human evolution. He extracted the DNA of the creature and modified it in able to merged it to human DNA. Without any hesitation he then merged his DNA to the DNA of the creature. He is willing to offer his body to attain his goal, thus sacrificing his body is necessary. After the merging, he was surprised because nothing in particular happened. But, he suddenly felt a surging power circulating through his body. He screamed in pain as his body is gradually changing. Darkness fell upon humans as the scream of the first demon engulfed the sky, seas, forest, and fortress.

Serra is a normal senior high school student who works really hard every night and weekend to pay off her parents' debts from loan sharks. But when she couldn't keep up with payments anymore, she decided to end her life. Surprisingly, she woke up in a different light-- in another world. What's more shocking was when she is addressed by one of the people as the demon king's bride.

When we were small, a witch named Sybil predicted that my sister would not live past sixteen. Since then, every eye in the family turned toward her. All the love in that house gathered around Aurora and stopped there. Whatever she wanted, whatever she wanted to do, our parents backed her completely. Every scrap of tenderness and every resource they had went to her, while I was left out in the cold, and the things that should have been mine were handed to her too. Even so, I never complained, not once. I knew my sister was someone to be pitied. Then the day of the prophecy came, the day she turned sixteen, and I was the one who ended up poisoned with wolfsbane, of all people, hanging on the edge of death. My parents were busy with her. They decided I was making a scene, and they ordered the guards to throw me out of the castle. My arms and legs had no strength left. I dragged myself toward the doors and called out in a shaking voice, "Dad, Mom, let me in, please, it hurts so much..." Instead, from behind the doors my father's gentle voice said to my sister, "Don't worry, sweetheart. The one causing trouble has been put out. No one is going to take your parents' love away from you again." Hearing that, something in me died for good. With the sound of my family fussing over her drifting through the door, I slowly closed my eyes.

When my sister and I were born, a prophet foretold that my sister would fall into a deep depression because I was more gifted than she was. On the day of the Fire Dragon Clan's Trial, she would throw herself into the frozen lake and never resurface. To protect her, my parents locked me in the freezing chamber on the day of the Trial. I knelt and begged them until my knees bled. My mother shoved me inside and sealed the door from the outside with a barrier. "You know your sister will die because of you, and you still insist on taking the Trial? How is that anything but trying to get her killed?" The chamber had already dropped to a hundred and twelve degrees below zero, yet I was wearing nothing but a short-sleeved shirt. I threw myself against the barrier, desperate to break out. "Mother, it's freezing in here! Please let me out!" "You're a fire dragon. A little cold can't hurt you. Who are you trying to fool?" My mother's voice was edged with impatience. "The barrier blocks your magic, but we didn't even turn on the refrigeration system. Your sister will be safe soon. Can't you think of her for once?" The sound of their wingbeats faded. My scales cracked from the cold, and blood dripped onto the floor. The barrier had sealed away my magic, and the chill quickly sank deep into my bones. I knelt on the floor as my body stiffened, inch by inch.

My family has always considered me a harbinger of misfortune. It's all because I can see a countdown to my relatives' deaths. I tell them when my grandfather, father, and mother will die. It all comes true due to various accidents. My three brothers hate me to the core because they think I cursed my parents and grandfather. My mother actually dies after giving birth to my younger sister, but my brothers dote on her to no end. They say she's their lucky star because everything goes well for the family after she's born. But didn't Mom die while giving birth to her? On my 18th birthday, I see my death countdown when I look at myself in the mirror. I buy an urn I like and prepare a meal. I want to have one last meal with my brothers, but none of them show up even when the timer hits zero…
