平兵士は過去を夢見る

魔王率いる魔族が現れ、人類に大規模な戦争を仕掛けたとき、すべての希望は失われたかに思われたが、勇敢な英雄たちが形勢を逆転させ、魔王を倒すまでに至った。When the Demon Tribes led by a Demon King appeared and launched a massive war at mankind, all hope seems to be lost, until a brave group of heroes managed to turn the tide and even defeated the Demon King. John Serieux, a mid-ranked soldier of Worlds Resistance against the demons army, had fortunately been able to witness the Demon Kings fall by the Heroes, but also was unfortunately killed a moment after. Miraculously, he was still able to open his eyes, only to realize that his mind had been sent back to the past when hes still a baby! With all the memories of his adult years, the knowledge of many scientific breakthroughs during the war, and information of the upcoming great disaster all intact, John is determined to cultivate his potential efficiently and optimally to help change the future for the best.
