As the dark fortress of Azkaban stood ominously against the night sky, the sea crashed against the rocky outcrops, and the wind howled around him, but Sasuke remained focused. Making his way to the entrance of Azkaban, Sasuke reached the outer wards of the prison. He raised his hand and concentrated a burst of chakra into a single point, disrupting the enchantments that protected the prison.
With a flash, he was inside. The alarms blared, and the Dementors, Azkaban's infamous guards, glided towards him, their icy presence sending chills through the air. Soon, Sasuke started to feel the effects of the Dementors' presence. To control his emotions, he began using Occlumency, but the effect of this technique was minimal. All the bad memories started to surface in his mind. While he would have liked to use a Patronus, he believed he could not, so he never tried to learn it. Making a hand seal, he unleashed a powerful giant fireball, but as expected, it had little effect. Now that the little test was over, Sasuke's Sharingan spun as he looked at the Dementors. He began to forcefully control them—10, 20, 50, and then 100. After a few more, feeling it would be hard to control any more, he started to use the ones he had already controlled to make his way further inside Azkaban.
Watching Sasuke control the Dementors, most of the Aurors had terrified expressions. They wanted to go and stop him, but fearing they might also be controlled, they started to run away. As Sasuke moved deeper into the labyrinthine corridors, the cold, damp air clung to his skin. His Sharingan scanned the surroundings, searching for what he was looking for. Creating multiple shadows, he sent them to search. In a few minutes, one of the clones found Greengrass. He arrived at a dimly lit cell. Inside, he saw a woman with long, brown hair, her eyes filled with defiance. It was Clarissa Greengrass. Transforming the bars to create an opening in the cell, he entered inside and started to drag Clarissa Greengrass out,who was still confused.
While they made their way through the corridors, one of his clone saw a woman with wild, dark hair and a manic gleam in her eyes. It was Bellatrix Lestrange.
"Bellatrix," Sasuke's clone muttered under his breath.
Bellatrix looked up, her lips curling into a sinister smile. "Well, well, what's this? A little kitty lost on the road?" she taunted.
Opening the door with a transformation, Sasuke said coldly, "Oh, I am going to turn you into a little puppy."
Bellatrix laughed, a chilling sound that echoed through the corridor. "Why don't you come near me and let me fix your little brain?" Without any care, Sasuke got near her, and before she could do anything, he fixed her in place. As he got near her disgusting mouth, he used magic to remove all her teeth, which had turned completely black. Then, taking out a healing potion, he forced it into her mouth. As she started to heal, he stripped her and cast a cleaning spell. Feeling it was not enough, with one hand he created a large water ball mixed with soap. He put the entire Bellatrix inside and started to spin the water like a washing machine.
Finally, after the washing was complete, Bellatrix was completely clean. Though she was not okay, she started to cough from the water. After the coughing stopped, she glared at Sasuke. For the first time, she felt such helplessness.
Bellatrix's eyes gleamed with rage, Unfazed by her glare, Sasuke proceeded to dry her with a flick of his hand, securing her in place magically to prevent any escape attempts. With this, the clone dispersed seamlessly, its memories seamlessly integrated back into Sasuke's consciousness, living her completely naked.
