Sarina Sonoda

Sarina Sonada is a classical literature teacher at Amanogawa High School who is also Gentaro Kisaragi, Kengo Utahoshi, and Yuki Jojima's homeroom teacher. It is later revealed that she is the human identity of the Scorpion Zodiarts, a Horoscope who distributes Zodiarts Switches among the students.

Personality
Sonada 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. Unfortunately, this also lays the groundwork for the Scorpion Zodiarts in its distribution of Zodiarts Switches.

As the Scorpion Zodiarts, Sarina becomes more brutal and manipulative. She uses the switchers' desire for personal vengeance against another student or the school to become Zodiarts. 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.

Abilities
As the Scorpion Zodiarts, Sarina becomes a dangerous force to be reckoned with, surpassing normal Zodiarts in power. She is adapted in fighting with her legs and the stinger on the back of her head. The Scorpion Zodiarts has also demonstrated the ability to summon Dustards.
