Backstory: Born to a rather poor family, Miyaji lived in a small cottage quite a distance from society. When his father died of illness, he became the provider for the house, as his mother began growing weak as well. The accommodations of his house were insufficient, especially in the winters, so during the cold seasons, he found shelter in the warmth of the campfire outside, and his method of relaxation due to the exhaustion of providing for his mother, his younger brother, and himself was meditation next to the fire. One day when he was 14 years of age, Miyaji heard rumor of a demon that had attacked the nearest village, leaving no survivors. Later on in the week, when he had been out hunting, his family fell victim to the demon as well, and neither of his remaining family members survived. As the demon had already disappeared, Miyaji had no way of tracking or even recognizing the demon who killed his family, so he was forced to put his old life behind him and start anew. Wandering through the country with only his clothes and naginata, he stumbled upon the abode of a former Flame Pillar, who agreed to train him. After studying under the tutelage of the retired Demon Slayer for three years, the Pillar eventually died of old age, his final wish being for Miyaji to pass the Final Selection on Mt. Fujikasane and succeed him.
