Araki Seriko was born into a lesser-known branch of the Yurami family, but he quickly proved himself to be a promising samurai. His parents had both been killed in a raid when he was a child, and he was taken in by his uncle, who was a trusted advisor to the current warlord Hakari Yurami. It was under his uncle's guidance that Seriko began to train as a samurai and learned the ways of the Yurami clan. Seriko quickly rose through the ranks, thanks to his natural talent and hard work. He proved to be a fierce warrior on the battlefield, but also a skilled diplomat and strategist. He was often sent on missions outside of the clan's territory to negotiate with other samurai and resolve disputes peacefully.
It was during one of these missions that he met Oda Yurami, who was also on a diplomatic mission for the clan. The two quickly became close friends, bonding over their shared love of combat and their desire to serve their clan with honor and distinction. Araki's loyalty to Oda was unwavering, and he quickly became one of Oda's most trusted advisors. He often accompanied Oda on missions, serving as his bodyguard and offering counsel whenever needed. Despite his high status within the clan, Seriko was known for his humility and kindness. He was respected by his fellow samurai for his honor and integrity, and was beloved by the common people for his generosity and compassion.
Araki was married to a fellow samurai, a woman named Tatsuko, and the two had a son together named Kazuo. He often spoke of his family with great pride and affection, and his devotion to them was matched only by his devotion to his clan and his close friend Oda.
