Wielding two swords with such grace, precision and power, Sōki is soon referred to by townsfolk as "Oni of the Ash". He is also called the "Black Oni" due to his extreme resemblance to the Oni God.

Birth
Hideyasu was born Tokugawa Ogimaru in 1574, the 2nd son of Tokugawa Ieyasu, by Ieyasu's concubine, Lady Oman. Oman is said to have given birth to twins, and that Ogimaru's brother succeeded Oman's father as priest of Chiryū Shrine in Mikawa Province. He was born near Hamamatsu Castle, in Ofumi Village.

Oman was a servant to Lady Tsukiyama, Ieyasu's first wife. After Ieyasu impregnated her, he feared Tsukiyama's wrath, and so he sheltered her in the home of his retainer Honda Shigetsugu. Ogimaru was born there.

The young Ogimaru was, for some reason, disliked by his father Ieyasu. It was not until age three that he met Ieyasu, and even that meeting, cold as it was, was not arranged by the father, but instead by Ogimaru's half-brother, Matsudaira Nobuyasu. After Nobuyasu's execution by order of Oda Nobunaga, Ogimaru would have been the next in line to inherit the Tokugawa headship; however, as part of the peace negotiations following the Battle of Komaki-Nagakute, he was given in adoption (in reality as a hostage) to Hashiba Hideyoshi. Coming of age while living with Hideyoshi, Ogimaru then took the name Hashiba Hideyasu, which combined the names of his adoptive father and biological father.

Battles
Hideyasu took part in his first campaign during the subjugation of Kyushu in 1587, leading the assault on Buzen-Iwaishi Castle. He also received honors for his distinction in the pacification of Hyūga Province. Hideyasu also took part in the Siege of Odawara (1590) and the Korean Campaign (1592). His successes in these campaigns earned him respect as an able field commander, despite his young age.

In 1589, a son was born to Toyotomi Hideyoshi, and so Hideyasu was given in adoption the following year to Yūki Harutomo of Shimōsa Province. Marrying Harutomo's niece, Hideyasu succeeded to the Yūki headship and its 111,000 koku landholding.

Later Years
Following the Battle of Sekigahara, he received a transfer from the fief the Yūki family held in Shimōsa Province (assessed at 101,000 koku) to one in Fukui (670,000 koku). In 1604, he took the surname Matsudaira. When he died in 1607, his first son Matsudaira Tadanao succeeded him.
