The father of Queen Ami and Emi.

Yoshiaki was born to Lady Hitomi and Lord Ryota of the Hisakawa noble house. Since he was a child, he took an interest in mechanical things and botany. Being their only son, his parents prepared him to meet Queen Tomomi, and hoped that they could find love eventually. Luckily, Yoshiaki and Tomomi’s friendship eventually did evolve into true love, embracing their differences between each other and appreciating each other’s interests.

Yoshiaki, much like his wife the then-Queen Tomomi, is quite shy and reserved, but loves his wife and daughters dearly and will do anything for them. Because of his knowledge in how mechanical things work, he was known for creating many different timepieces and mechanical dolls found throughout Omori Palace. Much like how Ami resembles Tomomi, Emi in this case looks a lot like Yoshiaki.

However, Yoshiaki went missing one day without explanation. Sadly, after three long days of searching, he was found dead in the cypress woods north of Omori Palace, with the cause never being confirmed.
