Yuuya Tenjou grows up surrounded by bullying and neglect, even from his own family, with his grandfather the only person who ever treats him with genuine affection. After his grandfather dies, Yuuya discovers a hidden door in the house leading to another world and the abandoned home of a great sage, filled with extraordinary weapons, crops, and game-like abilities.

Fighting monsters there raises Yuuya’s level and transforms his strength, body, and confidence, with the surprising benefit that everything he gains carries back into the real world. Between a new school, opportunities he never imagined, and adventures beyond the door, Yuuya tries to remain the kind person he has always been while using his new power to choose the shape of his life for the first time.
