However, veteran readers of the lore know this version was broken. It was a "false" Bankai. Why? Because Ichigo had not yet accepted his Hollow side. At this point, he believed "Zangetsu" was the old man in the cape (who we later learn is actually Yhwach —his Quincy power). By repressing his Hollow (the true source of a Soul Reaper’s instincts), Ichigo’s Bankai was spiritually splintered. The massive speed boost came at the cost of long-term durability, foreshadowed when his Bankai cracked slightly against Byakuya’s final attack.
Finally, we arrive at the definitive answer to any query: The Thousand-Year Blood War (TYBW) arc. Here, Tite Kubo completely reconstructs the lore.
Ichigo descends into the depths of the Royal Palace with Nimaiya Oetsu, the creator of the Zanpakuto. In a brutal sequence, Oetsu reveals that Ichigo has been using an "asylum" of a Zanpakuto.

His massive, cleaver-like Shikai (the original Zangetsu) shattered and reformed into a sleek, black nodachi (field sword) with a tenugui cloth wrapping the hilt. His traditional Shinigami shihakusho was replaced by a form-fitting longcoat.
In the sprawling pantheon of Bleach , a Shinigami’s Bankai is the ultimate testament to their soul. It is not merely a power-up; it is the crystallized truth of their being. For Ichigo Kurosaki, the moment he first uttered “Tensa Zangetsu” (Heavenly Chain Cutting Moon) was a radical rejection of every Bankai trope Tite Kubo had established. Because Ichigo had not yet accepted his Hollow side
However, the Lost Agent arc is vital because it sets up the final truth: The Soul Reaper powers Shinji gives him are merely a "key." Ichigo’s true Bankai cannot be given; it must be forged from acceptance.
