Was Captain Ailin strong?
There was no need to question that.
Even Aizen Sosuke, after fusing with the Hogyoku, had been defeated head-on by Captain Ailin.
Moreover, according to Aizen Sosuke, Captain Ailin had not even used his full strength during their battle.
No matter how strong Yhwach had been before, in the captains' perception, he was at most comparable to Aizen Sosuke in his third stage.
As long as Captain Ailin was willing, Yhwach would have no room to resist.
But unfortunately, Captain Ailin seemingly had no intention of personally acting against Yhwach.
Byakuya Kuchiki, Toshiro Hitsugaya, and Rukia had the most say in this matter.
With the arrival of the Thousand-Year Blood War, all three of them had realized that everything Teacher Ailin had taught them decades ago had been preparation for this battle against the Quincy.
Teacher Ailin seemed to possess some ability, much like Yhwach's, that allowed him to see through the future.
The clearest example was that after they had learned Bankai, Teacher Ailin had still made them train, bluntly telling them that there were countless abilities in this world. Even if they encountered circumstances in the future where they could not use Bankai, they had to possess the strength to deal with them.
Both Byakuya Kuchiki and Toshiro Hitsugaya had fought Ailin against Zanpakuto abilities similar to their own Bankai abilities.
After suffering the Quincy's attack, not only Byakuya Kuchiki but even Toshiro Hitsugaya felt that, in the future Teacher Ailin had seen, their Bankai had likely already been stolen by the Quincy and used against them in battle.
However, under Teacher Ailin's guidance and through their own diligent training, that "future" had not come to pass.
On Byakuya Kuchiki's side, even without using Bankai, he had directly suppressed As Nodt.
