The person who was reincarnated as a baby from the present day was an "old man" who studied Yakuro Chigen-ryu and developed a respect for the tragic warlord Kitagatake Akie who died at a young age because his eyes were glued to Kitagatake Akiie, played by the beautiful girl idol Kumi Gota in the Taiga period drama "Tahira". The reincarnated baby of such an old man was Oda Nobuo. He was adopted by Kitada Nobunaga at the behest of the Warring States overlord Oda Nobunaga. However, he was unable to organize the whole family and allowed his adoptive grandfather Kitahata Tamakyo to plot against Takeda Shingen's southward advance. He was ordered by the aggrieved Nobunaga to kill Kitadatake, and he meekly obeyed. Moreover, after that, he alone launched a war in Iga country, resulting in the death of a capable vassal, was reprimanded by Nobunaga and caused the Tensho-Iga Rebellion, burned down the Azuchi Castle of Honnoji Temple, and was a fool known as the "Sengoku Blind Man", leaving only a small amount of territory to future generations.
