After years of being apart, Ryou finally reunites with his long-lost father, whom he hasn't seen since infancy. However, he suddenly finds himself transported to the late Shouwa period, 22 years in the past. In this unfamiliar world, he comes face-to-face with Konomi, his father who is shockingly only three years younger than him. Struggling to adapt to his surroundings and finding himself plagued with uncertainty, Ryou is left wondering if he will ever be able to return to his own time. As he navigates this new reality and searches for a way back home, he also finds himself experiencing a wave of emotions he never thought possible. With its rich history and unique storyline, this is the initial volume of the acclaimed Reimon series.
