Shion Tomori

As the student council president of Spica, this character possesses a sharp and calculating nature, always plotting her next move. Despite this scheming, she maintains a relatively moderate personality, avoiding extreme actions or outright blockage, which sets her apart from her friends Kaname Kenjō and Momomi Kiyashiki. Her primary goal is to ensure a Spica attendant becomes the next Etoile, and she is actively trying to persuade Amane Ohtori to accept this role.
