Shibata Katsuie, also called Gonroku, was born in Kamiyashiro village, Owari, now located in Meito-Ku, Nagoya City. Initially, he pledged allegiance to Oda Nobunaga's younger brother, Oda Nobukatsu, and participated in Nobukatsu's scheme to usurp his elder brother's power. Katsuie led the charge against Nobunaga in the Battle of Ino in 1556 but was defeated. While Nobunaga had his younger brother executed, Katsuie was spared. Despite their past conflict, Katsuie became one of Nobunaga's commanders, earning a reputation for bravery and loyalty.
Katsuie's military career was marked by notable victories, such as his escape from the besieged Chokoji Castle during the Battle of Anegawa in 1570, where he demonstrated exceptional leadership by destroying the remaining water urns to prevent retreat. After this, he was tasked with establishing himself in Echizen Province (modern-day Fukui Prefecture) and constructed Kitanosho Castle, boasting a nine-story keep, the largest in Japan at the time.
Following Nobunaga's assassination at Honnoji in Kyoto, Katsuie engaged in battles with Uesugi Kenshin's forces and participated in the siege of Matsukura. His involvement prevented him from joining the pursuit of Akechi Mitsuhide, Nobunaga's killer.
During the Battle of Shizugatake, Katsuie supported Oda Nobutaka, Nobunaga's third son, as heir against Hideyoshi's preferred successor, Samboshi. Snowed in and facing Hideyoshi's advancing armies, Katsuie retreated to Kitanosho Castle. In the face of imminent defeat and encircled by Hideyoshi's troops, Katsuie commanded his daughters and wife, Oichi (interestingly, Nobunaga's sister), to seek refuge under Hideyoshi's protection.However, Oichi refused, and in a tragic end, Katsuie and Oichi committed seppuku together, with Katsuie initiating a fire that consumed Kitanosho Castle along with their bodies.

Norikage came from the ancient samurai clan of Asakura, whose members considered themselves descendants of Prince Kusakabe, son of Emperor Tenmu (631–686). He was the eighth son of daimyo Asakura Takakage and was named Kotaro in childhood. Over time, Asakura Norikage became the pillar of the Asakura clan and was undoubtedly its most talented commander during that difficult period when the clan was experiencing internal difficulties, uprisings by the Ikko-ikki sect, and instability in the lands surrounding the capital. Although Norikage himself was never a daimyo, he served as an advisor to three generations of Asakura clan leaders. He spent his entire life on military campaigns.

Asai (Azai) Nagamasa

Asai Nagamasa inherited power from his father, Asai Hisamasa, when he was only fifteen years old. Both brave and impulsive, he proved himself a capable commander, managing to regain lands from the Rokkaku clan that had previously been lost by his father. After a territorial dispute with Oda Nobunaga over the province of Mino, Nagamasa formed an alliance with Nobunaga and married his sister Oichi, who was famous for her beauty. In 1570, when Oda Nobunaga declared war on the Asakura family, Nagamasa sided with the Asakura because he had long-standing ties with them. This unexpected move threatened Nobunaga's invasion of the Asakura lands by threatening him from the rear. Oda managed to save his army, not without the help of Tokugawa Ieyasu, but relations between Nobunaga and Asai were permanently damaged.

Amago Tsunekisa

The Amago clan (also spelled Amako) was founded in 1392, when Sasaki Takahisa, who was orphaned at the age of three, took the new surname Amago, meaning “son of a nun,” in honor of the nun who raised him. Since the Sasaki family descended from Emperor Uda (866–931), the Amago clan traced its lineage back to this emperor. From around 1396, the Amago clan's headquarters was the mountain castle of Gassan-Toda in Izumo Province. Until the start of the Onin War, the Amago clan remained a minor clan in the service of the Kyogoku clan, which was also a descendant of the Sasaki clan. The Amago clan historically held the position of vice-governor of Izumo Province.
