Natsuki Yura, misunderstood for having his crush stolen by his womanizing childhood friend, Yuto Miyahara, fled in distress and was summoned to another world as a hero.
Six years passed in this brutal other world. After surviving harsh days and finally defeating the Demon Lord and the behind-the-scenes Demon God, he returned to Earth. To his surprise, time rewound to six years ago, right when his childhood friend introduced a girl he didn't even like as his girlfriend.
Enjoying the comfortable days in Japan, far better than the other world, Natsuki is suddenly confronted by confessions from his brainwashed and foul-mouthed step-sister, his childhood friend, and the neighborhood lady, all saying, "Actually, I've always liked you." However, he dismisses them saying, "I'm not interested in any of you."
During this time, the spiritually powerful Minazuki family noticed Natsuki's abilities and began to surveil him, leading him to discover Earth's fantastical elements and become deeply involved.
Beloved by trouble and embroiled in battles, he encounters yokai, monsters, demons, deities, and even aliens. Natsuki's everyday life becomes increasingly chaotic.
It's a story about Natsuki Yura, who fought as a hero in another world, returns to Earth to enjoy his youth, wielding the power of a hero and meeting lovely heroines.
