Arc 11Reikaku and the Quincy Threat
Ailin’s Reikaku fought Aizen’s Soul Soldier while the Seireitei confronted the signs of Yhwach’s return and Ailin strengthened himself for the coming war. As Ichigo began training as a Soul Reaper, Yoruichi told Ailin that Urahara had placed the Hogyoku in Shino’s Gigai to draw Aizen out, and Ailin agreed to remain an observer.
- Ailin’s Reikaku emerged from Inaba Kagerōza’s laboratory, entered the Gokuto, and fought Aizen’s Reikaku while shielding Karakura Town with his Bankai.
- After Ailin’s final Zanpakuto attack dispersed Aizen’s Reikaku, Inaba subdued Ailin and returned him to a nutrient tank, while Ailin learned that Aizen had begun cultivating White Hollow.
- Isshin Shiba followed White Hollow to the Human World, where he was wounded and saved by a student-uniformed girl, while Mayuri later reported him dead and Toshiro became acting Captain of the Tenth Division.
- Ailin rescued Sogen Ishida from Mayuri’s Hollow attack and warned him that he had only a few years to live, prompting Sogen to teach Uryu Ishida before sacrificing his life to protect him from Schrift.
- Mayuri accused Ailin of helping Yhwach regain power, but Ailin explained that he had honored his treaty with Sogen, and Yamamoto announced that Yhwach would attack in nine years.
- Ailin battled Zaraki, who awakened Nozarashi, then trained against his Bankai clone in Unlimited Blade Works and used Reinforce to strengthen his body.
- Ikkaku and Yumichika confronted Ichigo over Shino’s borrowed Shinigami powers, but Urahara stopped their fight and promised to protect them while expecting Shino’s power to return naturally.
- Yoruichi told Ailin that Urahara had placed the Hogyoku in Shino’s Gigai to lure Aizen out, and warned him that Yushima Oshu had developed powerful Soul Soldiers, including one that had matched Ailin.
