When 47-year-old single programmer Ritsu Hisahashi opens his eyes, he finds himself reincarnated\r\nas a boy named Mika in a poor village in another world. In a world where magic called [God's\r\nMiracles] exists, he leverages his knowledge from his previous life, his drive to take action, and his\r\nthirst for discovery-secretly training his magic alone, unnoticed by the adults...
