Sayo, driven by her determination to regain the upper hand, found herself in one of her secret headquarters. Her frustration with Amane, Fuji, and Itsuki's unmatched power pushed her to consider drastic measures.
**Sayo:** (with determination) "I need to understand how they've become so powerful."
She turned her gaze toward the three unconscious figures in a laboratory, her scientists working diligently around them.
**Sayo:** (commanding her scientists) "Create a drug, something that will make them obedient to my every command."
Her scientists nodded, understanding the urgency of the task at hand. They set to work on a dangerous experiment, concocting a potion that would bend Amane, Fuji, and Itsuki to Sayo's will.
Izumi, accompanied by Myamura and Elite, immersed themselves in deep thought as they pondered the whereabouts of Amane, Fuji, and Itsuki. The mystery of their captors' location weighed heavily on their minds.
**Izumi:** (thoughtful) "Where could they be?"
Myamura, Amane's teacher, observed Izumi's contemplation and offered words of encouragement and recognition of his abilities.
**Myamura:** "You inherit not only your father's strength but also your mother's intelligence, kid. You know where to start."
Izumi's face brightened as a clue began to form in his mind. There was one building, sealed off long ago, rumored to be a place where Sayo conducted her darkest deeds.
**Izumi:** (with determination) "I think I might have an idea. There's an old building, sealed off for years. Sayo used to use it for her secret operations."
Elite, Fuji and Itsuki's teacher, affirmed Izumi's hunch and rallied them towards a common purpose.
**Elite:** (resolute) "You're onto something, kid. Let's head there, rescue Amane, Fuji, and Itsuki, and put an end to Sayo once and for all."
Their resolve firmly set, Izumi, Myamura, and Elite embarked on a path that would lead them to the secret building and the final showdown with Sayo.
Standing before the sealed building, Izumi, Myamura, and Elite shared a determined glance. They knew that confronting Sayo and rescuing Amane, Fuji, and Itsuki was a dangerous mission, but they were ready to face whatever challenges lay ahead.
With a silent nod of agreement, they decided to take the direct approach and attack through the front door. It was time to put an end to Sayo's reign of terror and reunite their loved ones. With their domains activated and their spirits unwavering, they approached the entrance, ready to face whatever awaited them inside.
