The spiritual pressure on this ordinary Zanpakuto had only barely reached the threshold of Captain-level.
A Zanpakuto of this caliber was slightly inferior even to the Zanpakuto wielded by Kensei Muguruma, Aikawa Love, and the others.
But why was this the one left until last?
Could this Zanpakuto's ability be even stronger than all the previous ones?
Under everyone's watchful eyes, the spiritual pressure on the Zanpakuto was completely condensed into its blade.

A Reikaku, plainly speaking, was merely a defective product cultivated in a laboratory.
After a Reikaku died, its Gigai would shatter, and the Reikaku would disperse into spiritual particles along with it.

"Sorry, Hiyori, but I can guess what the attack was."
"That Zanpakuto pierced through Aizen Sosuke's body at a speed beyond our perception, then entered that golden
