From there, now a member of the Horoscopes, Sonoda became a teacher as she proceeds to find ideal students that would have the potential to become the remaining eight members.

Ms. Sonoda would later assume her Zodiarts form to fight off Kamen Rider Fourze to keep him from meddling Chameleon Zodiarts' revenge on Miu during the Queen Festival. After Chameleon's defeat; Ms. Sonoda is told not to destroy Fourze by Gamou, believing he can facilitate the Zodiarts' evolution.

Form
Sonoda has a kind and gentle demeanor which made her popular with the students of AGHS. She believes in a friendly approach to the students in contrast to Chuta Ohsugi. As a part of Mitsuaki Gamo's inner circle, her task is to encourage individuality among students. However this pleasant personality is just a farce, getting students to talk out their problems to her so she can distribute Zodiarts Switches to them in her Horoscopes form if their plight is dark enough.
As the Scorpion Zodiarts, Sonoda reveals her more brutal and manipulative nature. She uses the switchers' desire for personal vengeance against another student or the school to become Zodiarts. By knowing the student, she can determine which of them have the potential to make their Zodiarts form evolve and become more powerful. However, as none of her Switchers have ever made it past Last One, she is either choosing the wrong Switcher, or just handing them out in a random pattern in hopes of getting someone able past Last One, like her teacher is able to do.
The Scorpion Zodiarts is not above using a former Zodiarts to become a Zodiarts again despite their protests, even to the extant of taking them by force. Among the Horoscopes, Sonada is the most loyal to Gamo and his cause; effectively being his right hand and living only to meet his expectations.
