Yes, Kill la Kill originated as a manga. It gained popularity and was later adapted into different mediums, with the anime being particularly well-known.
The story might be based on a real - life case where a doctor's actions led to the endangerment or death of a patient. It could be due to negligence, like misdiagnosis or wrong treatment. Or it could be a more sinister situation where the doctor had malicious intent. There are unfortunately cases in history where doctors have violated their oath and caused harm, but again, without specific details, it's difficult to accurately tell this 'the doctor will kill you now real story'.
Sure does! The official manga of Kill la Kill exists and offers a different take on the story compared to the anime. It expands on certain plot points and gives more depth to the characters.
The ending of Kill la Kill manga is quite intense. The main characters face their ultimate challenges and there's a resolution that ties up most of the storylines.
