After the meeting was over, Eero left the meeting hall, his mind already moving to the next steps, and returned to the 3rd residence tower.
Seeing Nel was playing with a few hollows the same size as her; they were chasing each other, their laughter a small, high sound in the enormous, silent palace.
Eero then waved his hand toward her and called her near him.
"What happened, brother?" Nel trotted toward him curiously, her head tilted.
Eero thoughtfully glanced at her broken mask and said, "Do you want me to repair the mask on your head?"
Nel was startled, and then she replied confusedly, "Can it be repaired?"
Eero nodded and replied, "Yes, it can."
Nel then happily nodded and said, "Yes, I want to grow up. Pesche told me when my mask is repaired, I will grow and become super strong, then I will protect Pesche, Dondochakka, and you, brother."
Eero nodded and patted her head. He then raised his right arm, and a black and gold zanpakuto appeared in his right hand, different from the white and purple hanging on his left waist. It was a silent materialization, a blade born of time itself.
"Temporal Sword, Sword of Time,"
Eero muttered thoughtfully, and the outer appearance of the zanpakuto changed; its sheath and hilt became transparent like a thin, long glass container with sand-like golden particles flowing inside, each grain shimmering with ancient power.
"The sand of time," Eero muttered, looking at the golden sand particles flowing inside the zanpakuto, and then he unsheathed his sword and put the blade above the Nel's shoulder amidst her curious gaze.
Time and Space Reversal Strike!!!
'If I put my sword on some mortals shoulders and activate this ability, then that human's age will reverse to a child or even a sperm before his birth, but it will have a different effect on her, simply winding back the clock on the damage to her spiritual structure,'
Eero thought to himself, looking at the Nel in front of him; suddenly an invisible layer spread and covered the Nel mask only and started affecting it; slowly visible changes appeared in the mask above her head, the shattered pieces fusing with a pale green glow.
Nel hurriedly closed her eyes, feeling the inflow of memory in her mind, a rush of forgotten battle and past identity, while her mask started repairing.
"It's effective," Eero muttered, a cold satisfaction in his voice, and then a green reishi pressure, thick and dense, spread around through the residence toward the whole palace outside. The sudden, immense pressure spike was brief, yet shocking.
Eero glanced at the Nel figure enlarged to an adult size instantly, a quick, silent distortion of her form, while his zanpakuto blade was resting on her shoulder, the mask on her head also repaired completely, its smooth, green surface whole again.
Bang!!!
Instantly a long green zanpakuto appeared hanging on the left side of her waist, the physical manifestation of her restored power.
"Brother, I have really grown up, and my Gomuza also returned." Nel opened her eyes brightly and spoke cheerfully, her voice now deep and strong, and then she leaped and hugged Eero tightly, crushing him between her two large, soft mountains.
Eero, speechless, glanced at her hugging him tightly, and he was suffocating between her two large mountains, the momentary spiritual discomfort a hilarious contrast to his power.
He smiled, and then the zanpakuto from his right hand dissipated slowly and disappeared, leaving behind the other zanpakuto hanging on the left side of his waist.
"You can get used to your recovered power, then you can claim your number three title back." Eero spoke and then backed away a little, trying to breathe normally. Nel released him and then her brow furrowed, shook her head and replied,
"I don't care about the title anymore; I will just stay with my brother now,"
Eero nodded, and then his expression became playful, sensing something. "Let's go; someone wants an explanation about the disturbance just now."
Knock!!!
Nel was also startled; then she turned and glanced at the residence door being knocked by someone.
Eero and Nel appeared outside, looking at the Gin standing outside and looking at them. A surprise flashed through the Gin's eyes as he looked at the Nel, the child now a powerful adult, and then his expression became thoughtful as he looked at the intact mask on her head.
"Ron, Aizen-sama sent me to call you in the throne room," Gin informed, looking at him and then Nel. "Please bring her also,"
Eero nodded, and then following Gin, both of them appeared in the throne room.
Aizen, standing with Tosen, was startled looking at Nel behind Eero, and then he smiled and said calmly, "Congratulations, your sister has recovered. I thought you would wait for the Hogyoku to be unsealed."
Eero shook his head and replied calmly, "After observing my true powers, I realized that I can repair her mask on my own; that's why I didn't wait for the Hogyoku to repair."
A surprise flashed through Aizen's eyes, and then he glanced at Eero and asked, "Can you show it to me?"
After speaking, Aizen walked forward, descended, stood in front of the Eero, and spoke, "In order to be fair, first I will show you my Zanpakuto special ability, then you can show me your resurrección."
Eero nodded, looking at his zanpakuto with an intriguing expression on his face. Aizen smiled, seeing Eero's interested expression, and then he unsheathed his zanpakuto, the blade a flawless, shining silver.
"Kyoka Suigetsu!"
After activating the shikai of his zanpakuto, a faint, barely perceptible ripple ran through the air, Aizen smiled seeing Eero successfully witness his Kyoka Suigetsu activation, and then he spoke,
Gin, standing far away, also smiled a little, looking at Eero watching the Kyoka Suigetsu so attentively.
"My Zanpakuto's special ability is Kyoka Suigetsu; once someone witnesses my Zanpakuto during the activation of this ability, his five senses are then under my control. If I want, I can introduce a fly as a dragon in his senses."
Aizen explained calmly, then his figure blurred, a quick, silent shift, and virtually disappeared and then materialized beside Gin in the upper throne area.
