Ashe was born as the eldest son of restaurateurs in the Gaspard region. He was happy with his parents and two younger siblings, often helping them at their restaurant, but his parents eventually died from a disease, leaving him as the sole provider. Ashe tried to work honestly for money, but still it was not enough. He turned to thievery, and though he knew it was morally wrong, continued to do so because he saw how happy his siblings were.

At age 10, he broke into a noble's mansion in order to rob valuables that he could sell to support his siblings. Inside, he found a book called Loog and the Maiden of the Wind. Enamored by the gallant looking knight on the front cover, he coveted it despite the fact he could not read. He was promptly discovered by the mansion's owner, but rather than have Ashe arrested, the noble opted to give him the book and teach him how to read. Having heard of his family situation, the noble, Lonato, adopted Ashe and his two siblings, giving them a chance at a better life, an act that Ashe was forever grateful to have received. He became quite close to his adoptive older brother, Christophe, as well.

However, three years later, Christophe was executed by the Knights of Seiros. Ashe was made aware that Catherine had brought him to the Knights for execution. Christophe's death greatly affected Lord Lonato, and he took a turn for the worse, though Ashe was unaware of how deep the impact was.

He holds great respect and gratitude towards Lord Lonato, who took him in, raised him as his own, and sent him to the Officers Academy despite being a commoner. He is a serious young boy, who studies and trains hard so he can become an outstanding adult like his benefactor.
