Kelvin Fujiwara is a HIKIKOMORI who cut himself off from the world after a tragic accident took his parents and younger sister when he was just 15. Following the loss of his family, Kelvin became a reclusive and distant person, showing minimal interest in anything outside his control, although he does care about what he can manage. Since that fateful day, he rarely smiles, and his life has only gotten tougher. Now at 25, a decade later, Kelvin has faced a lot of pain, sadness, and struggles. He's been let down by family, betrayed by friends, left by his girlfriend, dropped out of college, often lost jobs, and even dealt with bullying and harassment. Despite everything, Kelvin works hard to live a good life, hitting the gym regularly, learning new things, eating well, and taking care of himself, especially his appearance. His only vice is that he loves staying up late with a cup of coffee. There was even a time he stayed awake for three days just to finish the Call of Duty Modern Warfare series. But one night, right after he wrapped up Honkai Impact 3rd part 1, Kelvin gets hit with a terrible headache, and when he wakes up, he finds himself in a totally unexpected place. He's been reincarnated into the game he just completed.
