Karl Wagner is a disgruntled middle-aged instructor at the Bundeswehr Command and Staff College. He finds himself concerned about the direction which the German nation is headed in—just as he is killed by a terrorist attack. Only to awaken and find himself reborn as an infant, Bruno von Zehntner, the youngest son of a noble family renowned for its part in the German war industry a few years after the founding of the German Empire. Bruno, as he is now known, desires to rewrite history and ensure the German Empire emerges victorious in the coming century. And in doing so, finds himself entrenched in a world filled with Blood and Iron!
Bruno returned to the party not long after his conversation with the Prussian Princess. They would never speak again of what had been said in private within the snow-filled palace gardens, nor would there be any hostilities between them due to the awkwardness that had resulted from the misunderstandings of a teenage girl and her unrequited love.
In fact, Hedwig, Olga, and Sakura were all around the same age and would themselves be married off in the following years, forgetting all about whatever foolish notions they had towards Bruno. This did not mean, however, that the bonds Bruno had forged with their royal families as a result of these misunderstandings would disintegrate.
Rather, he would be far friendlier with all of them going forward, as any sense of unease caused by these misunderstandings was thoroughly gone, replaced instead with a sibling-like friendship.
