Rika Saionji was once a normal student at Suzaku High School before being chosen as one of the Seven Witches. Her power granted her the ability to erase memories, making her the most dangerous and influential among the first generation of witches. Aware of the heavy burden her power carried, Rika began to distance herself from others and operated more secretively than the other witches.

After the original witches’ powers began to resurface and cause unrest, Rika emerged from obscurity to protect her own goals. She viewed the chaos as an opportunity to create a more controlled environment one in which she could govern supernatural power rather than let it spiral. Though her intentions may have seemed cold, she genuinely believed she was acting in the school’s best interest.

Rika is a tall, attractive young woman with long dark brown hair, often tied up in a high ponytail, and sharp violet eyes. Her expressions typically remain neutral or mildly amused, giving her a composed and somewhat intimidating presence. As a student council leader, she maintains a clean and professional appearance, always dressed properly in the Suzaku High uniform with an air of authority.

Her posture, poise, and commanding gaze set her apart as someone who is always in control whether she’s leading the council or dealing with supernatural conflicts.

Rika is best described as cool, calculating, and composed. She carries herself with calm confidence and often approaches situations with logic rather than emotion. Though she isn’t outwardly cruel or aggressive, her pragmatism and willingness to use her powers for long-term benefit often create conflict with more emotionally driven characters like Yamada.

Despite her intimidating demeanor, Rika is not devoid of emotion. She simply places logic above personal feeling, believing that control and order are necessary to prevent chaos. She genuinely believes in managing supernatural forces responsibly even if it means making tough decisions. Over time, her more human side is revealed, particularly as she interacts with the second generation of witches and gradually steps back from authoritarian control.

• The Seventh Witch
  Rika is revealed to be the seventh and final witch in the original witch system, holding the power to erase memories. Her ability poses the greatest threat to Yamada and the others, as it allows her to undo all the bonds and progress they’ve made. She initially uses this ability strategically to keep the existence of witches a secret.

• The First Ceremony
  When Yamada decides to hold a ceremony to erase all witch powers, Rika becomes the final obstacle. She tests Yamada’s resolve, challenging his ideals and emotional attachments. In the end, she loses her power along with the other witches but accepts the outcome with grace, acknowledging Yamada’s sincerity and determination.

• The New Witch System
  In the aftermath of the ceremony, Rika doesn’t disappear from the story. Instead, she resurfaces as a key orchestrator behind the second set of witches, now assuming a more authoritative role. Temporarily acting as the Student Council President, she supervises the selection of new witches and aims to create a more structured approach to supernatural governance one that contrasts with the chaos of the original system.
