Shiranui Mizuki
He and Shiranui Mizuki first met around the time when they were 18 years old during the Osaka Crisis in 2010. They had known each other in the span of four months prior to Yukimura's first encounter against Nobunaga Oda, who was resurrected in the present day. Yukimura's hot-blooded personality, with a "charge-to-battle-headfirst" mindset, as Shiranui called it, clashed with here serene and calm personality, resulting in the first few months of their relationship being more akin to that of rivals than friends. Due to Nobunaga's ambition to capture Shiranui for reasons that were unknown at the time, Yukimura dedicated upon himself to protect her from danger, which was why he was seen by many enemies of Shiranui as the number one obstacle to capturing her.

Having never been in a relationship nor being that close to a girl, the fire samurai had been shy to the water Taimanin and was sometimes unsure on what he wished to express on her himself. However, during and especially after the Osaka Crisis, Shiranui and Yukimura realized that they loved the other and needed each other to survive. Despite the heavy burden that the two carry as a samurai and a Taimanin who fight evil wherever and whenever, they fully understood each other, though occasionally they would delve to tough disagreements in how they plan or fight. Two months after the Osaka Crisis ended and Nobunaga was defeated, Shiranui and Yukimura fully sealed their relationship as lovers and tied the knot together. According to Asagi, the two were a great power couple and strong partners, flowing perfectly in rhythm like "fire and water". However, over the years, especially at some time prior to Shiranui's capture, he and Shiranui became a little more distant from each other, but still maintained a strong family bond with their daughter, Yukikaze, as well as Rinko and Tatsurou, who they also viewed as children of theirs.
