Twin Star Exorcists - Characters & Cast

Initially, his motivation is simply to live a normal life away from exorcism. This evolves into a fierce desire to protect Benio and his new friends. Ultimately, his motivation becomes a grander ambition: to end the thousand-year war and ensure no more children have to become exorcists, thereby breaking the cycle of tragedy.

Rokuro begins as a traumatized boy who has completely abandoned his dream of being an exorcist after the Hiinatsuki Tragedy. His meeting with Benio and being forced into the Twin Star prophecy slowly reignites his desire to fight, not for glory, but to protect others. His arc is about reclaiming his purpose. He evolves from someone running from his past into a leader who confronts it, learning that his power isn't a curse but a tool to create a future where no one has to suffer as he did.

Her primary motivation is to become the strongest exorcist to defeat Kamui, the Basara who killed her parents. As she grows closer to Rokuro, her motivation shifts. She begins to fight to protect him and their shared dream of a peaceful future, moving beyond personal vengeance to a more selfless cause.

Benio starts as a cold, stoic, and incredibly powerful exorcist singularly focused on avenging her parents' deaths. Her world is one of duty, pride, and solitude. Her relationship with Rokuro forces her to open up emotionally. She learns the importance of teamwork, friendship, and relying on others. Her arc is about discovering that there is more to life than revenge and duty; it's about finding love and a new reason to fight—for the future, not just the past.

Yuto is driven by a profound obsession with Rokuro and a desire to attain the ultimate power by merging with the Yang energy. He seeks to prove his own strength and philosophy by crushing Rokuro, whom he sees as his ultimate rival and object of fixation.

Yuto is Benio's estranged twin brother and the orchestrator of the Hiinatsuki Tragedy, making him a dark reflection of both protagonists. He serves as the primary antagonist for the first part of the series. His arc is tragic; he is consumed by a nihilistic desire for ultimate power, born from his own twisted ideals. He doesn't develop in a redemptive way but rather serves as a catalyst for Rokuro and Benio's growth, representing the path of power through hatred that they must overcome.

His motivation is to protect the world from Kegare and to ensure his students, particularly Rokuro, are strong enough to survive the brutal life of an exorcist. He is also driven by a deep-seated, though poorly expressed, love for his daughter Mayura.

Seigen is one of the powerful Twelve Guardians and was Rokuro's former master. He initially appears cold, ruthless, and distant, especially towards Rokuro and his own daughter, Mayura. Throughout the series, his harsh exterior cracks to reveal a deeply caring mentor who pushes his students to their limits because he believes in their potential and wants to protect them. His arc involves confronting his past failures as a father and a teacher, eventually sacrificing himself to protect the new generation.
