Kousei's eyes work—medically, physically, neurologically—yet the anime treats his blindness as almost embarrassing to mention.

When he sees again in the final arc, there's no therapy subplot, no medication, no structural acknowledgment that something broke in his brain.

Watch the recurring motif of the recital stage. Each performance is shot as spiritual transcendence — lens flares, impossible lighting, the audience dissolving into watercolor abstraction — and the production design treats the concert hall as a space where physics bends toward feeling.

Music doesn't express emotion here. Music rewrites reality.

The script enforces this ruthlessly. When Tsubaki tries to reach Kousei through conventional support — being present, being practical — the show frames her care as insufficient, even suffocating. The only intervention that works is Kaori's performance, her dying body still producing sound, so Kousei's recovery isn't about processing loss or developing coping strategies but about witnessing someone else's aesthetic suffering and letting that beauty override his own neural dysfunction.

This is post-2010s Japanese anxiety crystallized: mental illness as a private moral failure correctable only through exposure to sufficiently pure art — no institutions, no medication, no doctors who might suggest the blindness has causes beyond the soul.
