Nearly 22 years after the Bleach anime first aired, the Thousand-Year Blood War arc is finally bringing the story to a close. This final chapter has been packed with major revelations that are reshaping how fans view familiar characters and their powers.
Right from the start, the finale surprised viewers when Genryusai Yamamoto unleashed a powerful Bankai before being defeated by Yhwach. Since then, a string of secrets have come to light. Kisuke Urahara finally revealed his Bankai, and Kenpachi Zaraki showcased his Bankai despite the story previously suggesting he would never possess such an ability.
However, one of the most striking changes involves Toshiro Hitsugaya. For a long time, fans believed Hitsugaya’s Bankai had a time limit tied to the 12 ice petals that appeared when he used Daiguren Hyorinmaru. Once those petals vanished, many assumed his Bankai would disappear as well.
The latest episode completely overturned that assumption.
Hitsugaya finally reaches his mature form

During the battle against Gerard Valkyrie, Hitsugaya, Byakuya, and Kenpachi were repeatedly overwhelmed. Hitsugaya seemed to reach the limit of his Bankai, a fact even Byakuya noticed.
Just when fans thought Hitsugaya was about to be knocked out, a crucial secret was revealed. The disappearance of the 12 ice petals does not mean his Bankai ends. Instead, that period is necessary for Daiguren Hyorinmaru to fully mature.
When the last petal vanished, Hitsugaya’s Bankai truly evolved. At the same time, Hitsugaya’s body transformed, turning him into a mature version of himself.
This revelation surprised many because fans had always believed that reaching this limit would weaken Hitsugaya or prevent him from fighting further. The truth is the opposite: this is when his power peaks.
The new form is more than just a visual upgrade

Hitsugaya’s transformation became even more impressive as the anime team introduced a new voice actor to portray his mature form.
Notably, this voice actor also lent his voice to Eren Yeager from Attack on Titan, making Hitsugaya’s mature debut even more memorable.
But this new form is not just about looks. Hitsugaya now claims that anything near him can freeze instantly. This ability was demonstrated directly in battle, showing that his mature Bankai is significantly stronger than before. According to the story, this form doubles the effectiveness of his Bankai.
A change that flips fan expectations
This new information might also explain why Hitsugaya has maintained a youthful appearance throughout the series. It’s possible that the maturation process of his Bankai’s spirit is linked to his own physical form.
Of course, it could also be a creative choice by the author to give the character a striking new look. Whatever the reason, the fact that Daiguren Hyorinmaru requires time to mature has completely changed how fans understand the limits of Hitsugaya’s Bankai.
