When designing Konohana Sakuya, Shigenori Soejima wanted to make her accompany the protagonist's Izanagi. Izanagi looks manly: He has a boys' school uniform, a knife, and he gives off the vibes of an Ōendan leader. Accordingly, Konohana Sakuya was designed to be feminine: She looks like a pom girl, she has cherry blossoms, and her color is pink.[1]
In Golden, Yukiko starts with Konohana Sakuya. It transfigures into Amaterasu upon maxing her Social Link, and can further transfigure into Sumeo-Okami during winter.
She was the daughter of the mountain god Ouyamatsumi. When she became Ninigi's wife and grew pregnant on the first night of their marriage, he accused her of infidelity. She stood in a burning hut, claiming the fire wouldn't touch her if she had been faithful, and emerged unscathed. Her emblem is the cherry blossom.
Trivia
Persona 4: Dancing All Night: During Yukiko's victory animation, Konohana Sakuya appears and has a saxophone solo. The saxophone is also the instrument Yukiko learned how to play for the Junes concert in Persona 4 Golden.
