Also remember this from earlier?
People who have mild or moderate aplastic anemia may not need treatment as long as the condition doesn’t get worse. People who have severe aplastic anemia need medical treatment right away to prevent complications.
People who have very severe aplastic anemia need emergency medical care in a hospital. Very severe aplastic anemia can be fatal if it’s not treated right away.
What does it conclude? Remember something? Kaori was hospitalised later on in the series; meaning: she was suffering from severe aplastic anemia.
And like I at the beginning of this article, the cause of her death was most likely operation failure and; as for why did it fail? Maybe she didn’t get a suitable donor for her Bone Marrow Transplant or it might have failed due to her deteriorating health.
That’s it for now. Remember, this was just a theory and there is no official news on Kaori’s illness and probably there won’t be any. While some people say it’s Bone Marrow Failure that she suffered from, others say it was ALS (Amyotrophic Lateral Sclerosis) due to their symptoms. But I strongly believe it was Aplastic anemia.
Still, Kaori’s death itslef was enough to kill me 🙁 .
Be sure to comment below if you have any other theories. Also request anything related to anime and we will get it done in no time.
