Ailin had no idea that while he was fighting Soifon, Aizen Sosuke had stabbed him in the back.
Only when he sensed that more than half of Soifon's spiritual pressure had been depleted, leaving her barely able to maintain her "Infinite Shunkō" state, did he directly tear apart the tornado surrounding her and point his right index finger at her waist.
"Bakudō #61: Six Rods Prison of Light!"
Golden light flew from Ailin's fingertips, splitting into six beams that instantly shot around Soifon and transformed into six curtains of light, sealing off her Sōtsubame.
With Soifon's spiritual pressure, there was no way she could break free from the Six Rods Prison of Light Ailin had cast. She was pinned in midair.
"Hadō #4: Byakurai!"
"Boom!"
Another bolt of lightning shot from Ailin's index finger, passing by Soifon's ear and scorching some of the hair beside her left ear.
"You lost, Captain Soifon."
"Mm. I concede."
After hearing Soifon concede, Ailin dispelled the Six Rods Prison of Light and went with her to stand before Genryūsai Shigekuni Yamamoto.
"Captain-Commander, regarding Acting Captain Soifon's captain assessment, I personally believe that Acting Captain Soifon possesses the strength to serve as Captain of the Second Division."
"Indeed."
After Ailin acknowledged Soifon, Shunsui Kyōraku immediately spoke up. "Although Captain Soifon did not display her Bankai, the power of the state Miss Soifon showed just now was in no way inferior to a Bankai..."
"Mm, that is indeed the case."
Aizen Sosuke smiled. "In only half a year, Captain Soifon has improved so greatly under Captain Ailin's guidance. I wonder whether I might be fortunate enough to become the next person Captain Ailin instructs?"
"Hahaha, Captain Aizen, Captain Soifon's present strength is mainly the result of her own efforts. I merely gave her a little guidance.
