29-year-old programmer Suzuki Ichirou finds himself transported into a fantasy RPG. Within the game, he's a 15-year-old named Satou. At first he thinks he's dreaming, but his experiences seem very real. Due to a powerful ability he possesses with limited use, he ends up wiping out an army of lizard men and becomes a high leveled adventurer. Satou decides to hide his level, and plans to live peacefully and meet new people. However, developments in the game's story, such as the return of a demon king, may cause a nuisance to Satou's plans.

Faced with the relentless and unstoppable advance of the Soviet Red Army, from the spring of 1944 until the capitulation of the Third Reich in May 1945, the Nazis evacuated the labor, concentration and extermination camps, factories of pain and death which, during years of nightmare, they had established in the occupied eastern territories. Forced to travel enormous distances, thousands of people died along the way from hunger, thirst and exhaustion.
