"Lower limit? Upper limit?"
Byakuya Kuchiki murmured to himself.
Though it was his first time hearing these two terms, he quickly understood their meaning from Uncle-in-law Ailin's explanation.
The so-called "lower limit" should be the minimum level of strength he could bring out.
Conversely, the "upper limit" was the greatest strength he could wield.
In other words, the four Shinigami arts could ensure he had no weaknesses, while a Zanpakuto's ability could elevate one particular aspect of him.
"Uncle-in-law, I am willing to undergo your second round of training."
"What exactly is Captain Kuchiki doing?"
This had been the greatest question troubling most Shinigami in the Seireitei for the past two months.
Every day, they could sense the immensely powerful spiritual pressure of Captain Ailin of the Sixth Division.
Within the Seireitei, all captains were forbidden from releasing their Zanpakuto.
Hibiki Hoshino, the former Third Seat of the First Division, was a cautionary example.
Yet the captain of the Sixth Division had been using Bankai within the Seireitei for more than two months straight, and Captain-Commander Yamamoto had not reacted in the slightest. This left everyone puzzled. What was it that made Captain-Commander Yamamoto so indifferent to Ailin releasing his Zanpakuto?
They had no way of knowing that Captain-Commander Yamamoto turned a blind eye to Ailin's Bankai within the Seireitei for two reasons. First, Ginrei Kuchiki had told him that Ailin would leave the Soul Society and enter the Human World in three months. At that time, Captain-Commander Yamamoto could strip Ailin of his captaincy and exile him from the Soul Society on the grounds of repeatedly violating the ban, thereby enhancing his own authority.
Second, and more importantly—
Captain-Commander Yamamoto prohibited captains from fully releasing their Zanpakuto because their Bankai possessed immense power and could cause catastrophic destruction
