※The first volume has been published by Earth Star Novels. New characters have been added, and there have been significant revisions. I hope you enjoy it in comparison to the web version. The time is the Sengoku period, and the Hachinohe clan, which supported the northernmost Sengoku daimyo 'Nanbu' in Honshu, had a branch family called the 'Nitta' clan. Despite the name, it is pronounced 'Nitta' and not 'Niida.' As a minor samurai who doesn't even appear in historical simulation games, many people are likely unfamiliar with him. A man who built one of the leading construction companies in Aomori Prefecture in a single generation lost his life to a pandemic and found himself reborn as the second son of the Nitta clan at the Tanabe Castle (present-day Mutsu City) overlooking the Mutsu Bay. 《I have the knowledge, the wisdom, and the means to achieve it. All that's left is my will!》 His goal is to become the ruler of the Sengoku period and to realize the great 'Great Jipang'! With the banner of 'No Hunger, No Fear, No Trembling,' the man's ambition burns brightly. This is the love and ambition success story of a man born into a small local clan at the northernmost tip of Honshu. ※While historical research has been done, there are many unknowns about the Sengoku period in Oshu, so please bear with the parts that are a bit loose. ※There are many scenes of domestic affairs, such as the development of local specialties. While I have written within the technological limits of the Sengoku period, I would appreciate it if you could refrain from nitpicking. ※I have added the Gregorian calendar year after the era name for easier reading. ※To make it easier to read, I occasionally add furigana to names. ※This is my first 'historical novel,' so I would be grateful if you could read it with a warm heart.
