Allen had hoped that after being banished from the Duchy of Westfeldt, he could live a quiet and carefree life. But danger continues to rear its head, calling him back into action like the hero he was in his past life. His next mission is to uncover the truth behind the mysterious assassination of the general who bolstered the nation’s military might. Meanwhile, the blacksmith Noel strives to forge the perfect sword for Allen, one that surpasses even the Champion’s Hauteclaire, but raw power alone may not be enough to destroy enemies that lurk in the shadows. Allen’s wish will have to be put on hold yet again as he ventures once more into the thick of adventure.
