Ailin had a clear understanding of himself.
Was he strong?
Strong—very strong. He might even become extraordinarily strong in the future!
But becoming invincible in the world of Bleach was still, at least in Ailin's eyes, a distant prospect.
He possessed "Unlimited Blade Works," which allowed him to create "swords" with all sorts of abilities.
Especially in a world like Bleach, where Zanpakuto existed, Ailin could grant many abilities to a Zanpakuto and use them as its "Shikai" and "Bankai."
This was also acknowledged by the abilities of "Unlimited Blade Works."
Because in this world, those were abilities that belonged to "swords."
Yet, after years of dedicated research—well, after bringing out all the powerful weapons from his memories—even that could not make him "invincible" in Bleach.
Among them, the most impossible opponent was undoubtedly Ichibei Hyosube of the Royal Guard.
Ichibei Hyosube's very existence was equivalent to Soul Society itself.
The Spirit King had bestowed upon him the name "Monk of True Name Calling," granting him the ability known as "Name Is Power."
Everything named by Ichibei Hyosube possessed the "power" corresponding to its name.
The names of everything in Soul Society had been given by Ichibei Hyosube.
Furthermore, the fundamental nature of Ichibei Hyosube's existence was "black."
All "black" in the world belonged to him.
Through that essence, Ichibei Hyosube had nurtured the oldest Zanpakuto, one that had existed before Zanpakuto were even born—Ichimonji.
It could be said that aside from the Spirit King, Ichibei Hyosube was the "invincible" one among the Soul Reapers.
Only because Yhwach possessed an ability like The Almighty could he ignore the power of Ichibei Hyosube's "black" and "names" and defeat him.
Thinking of those two made Ailin feel somewhat pessimistic.
Perhaps only after meeting Tenshiro Kirinji and copying his Zanpakuto, "Kinjika," could he
