• Appearance: When Ichigo activates his Bankai, his traditional Shinigami uniform (black kosode and hakama) transforms into a sleek, black, form-fitting coat with red inner lining — often described as a red-and-black kimono or trench coat style.

• Origin: This outfit appears when Ichigo achieves his Bankai, the final and most powerful form of a Soul Reaper’s Zanpakutō (his sword, Zangetsu).

• First appearance: During his fight with Byakuya Kuchiki in the Soul Society Arc.

• Symbolism: The simplified, modern design of his Bankai outfit reflects the compressed and concentrated nature of his spiritual power — speed, control, and intensity instead of raw bulk.

Later versions (like Final Getsuga Tenshō and Thousand-Year Blood War arcs) modify this outfit slightly, but the core black with red accents design remains tied to his Tensa Zangetsu Bankai form.
