I Thought It Was My Second Life, But It Was Actually My Third!~I Will Challenge Unhappy History with Historical Knowledge and Domestic Efforts~

Born the second son of a baronial family plagued by misfortune, Takuhir became the head of the household at the age of 16 after successively losing his family to calamities.
Desperately working on domestic affairs, but being an ordinary man, he was unable to prevent the continuing disasters or restore his domain. He was called incompetent and defeated by a neighboring country’s invasion at the age of 20.
Pleading for the protection of his people in exchange for his own life, he awakened to magical skills at the moment of his execution and transferred himself to the past to redo everything.
Returning to the time of his birth as the second son of the baronial family, he also regained the sad memories of his first life, living and dying as a Japanese person.
Utilizing the historical knowledge gained in his second life in another world and the knowledge of modern Japan from his first life, he resolves to avoid disaster and save his family and companions in his third life.
However, being still a child, he cannot achieve overwhelming power or sudden reversals. He starts with steady proposals for domestic reform, earns funds, increases his allies, develops the town, and gradually accumulates power.
Can he change history and save his family?
Is there a bright future in this world of redoing?
The grand rebellion of an ordinary man, who has resolved to fight against a history that brings one disaster after another, now begins.
