Friedrich no Senjou - Shinku no Tensai Gunshi, Uso Kara Hajimeru Eiyuutan

Friedrich, a once-orphaned but brilliant young man, lived a quiet and peaceful life in a rural village. However, that peace was abruptly shattered by a raid from a band of thieves. While the villagers were consumed by despair, Friedrich stood apart—he stepped forward before the people and spoke:

"I am the son of a hero. If you follow my plan, we will surely win!"

This is the story of a young man who was once a nobody, rising to become a great hero whose name would be etched into history.
