Who Died In Demon Slayer

It was in the Era of Harmony, trillions of years ago, when Chaos first arrived. To stop all existence from growing rampantly and exhausting all sustenance, the Creator of the universe took on Chaos as its body, the void as its vigor, and black holes as its jaw—a combination to create a world-ending coffin, devouring the seas and setting lands aflame, reducing all to ashes! Later, millions of years ago, the gods waged wars against each other when the same coffin appeared out of nowhere, massacring their ranks and decimating the divine realm. Since then, it had gone missing, but its name continued to echo throughout the universe, leaving both gods and demons in fear! Millions of years later, a youth was buried alive and fused with the coffin where he was kept, and he became an undertaker whose name was heard throughout all worlds. "I'm really bad at saving lives, but I'm quite good with ending them," he said quietly with a cool visage. "I possess the Coffin of the Gods, and I can send anything and anyone to their deaths: humans, worlds… or even the gods themselves!"

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.

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…

On the day before the college entrance assessment, my three childhood friends have gone missing collectively. Because of that, my phone is swamped with phone calls. The parents of my missing friends keep wailing to me, "We've worked so hard our entire lives just so our sons can get into a great university!" My homeroom teacher, Mr. Levinski, begins pressuring me. "You're the class president, so you must find them! The college entrance assessment is a vital event that can determine how one's future will turn out!" Even my classmates and my neighbors keep texting me for more updates. But what they don't know is that I've already hung up on my friends' phone calls for help by using my revision for the assessment as an excuse. In my previous life, my childhood friends had already gotten bewitched by Lucille Reyes, a delinquent. They insisted on celebrating their coming-of-age ceremony at a nightclub because of her. I accidentally overheard Lucille plotting with her delinquent friends that they intended on taking nudes of my friends and extort money from them so that they couldn't attend the college entrance assessment the next day. So, I did everything I could to stop my friends, only to get kicked to the side. "Don't stop us from pursuing true love!" For the sake of my friends' future, I informed their families at once and had them brought into the exam venue by force. Finally, all three of my childhood friends got into prestigious universities. But Lucille, on the other hand, got beaten to death by the delinquents because she couldn't pay her protection fees due to her scheme getting foiled. My friends broke down mentally because of her death. They then decided to pin the blame on me. On our freshman year, my friends treated me to some drinks out of "gratitude", only for them to spike my drink. Later on, they tossed me to the same group of delinquents, who violated me in an alley. They even had the gall to record everything from the alleyway while keeping an eye out for the police. Thanks to them, my future was completely ruined. My parents committed suicide out of despair. To rub salt onto my wound, those friends showed up at the hospital with the video and backed me into a corner once again. "You owe Lucy this much!" In my despair, I ended up jumping off the rooftop. When I open my eyes again, I've returned to the day before the college entrance assessment. As I watch my friends excitedly discussing the nightclub party behind my back, I can't help but smile. In this lifetime, I choose to lock my door and sign the guaranteed admission agreement meant for Mephton University, the most prestigious university ever, without any hesitation. As for my so-called friends, they can enjoy their coming-of-age ceremony in hell.
