After remembering the entirety of his past, Akaza started to regret his actions both as a human and demon, realizing that he never respected his father's words to live an honest life and bloodied Keizo's precious Soryu Style by using it to murder others. He came to the realization that he hated himself for all of the times he wasn't there to save or protect those he loved, and that he himself was the person he really wanted to kill all along. With the knowledge that the people that he wanted to protect had already died a long time ago, Akaza lost the will to continue fighting as his pursuit of strength was already for naught and decided to end his own life. In his final moments, Akaza showed that he still had a lot of humanity left in him, remarking that Tanjiro's technique was magnificent and that he had lost fair and square, even smiling and feeling gratitude towards him for reminding him of his past.

In regards to himself) " I became a demon, lost my memories and again began seeking strength. There was nothing left I wanted to protect. I didn't even want to continue living in a world without my family. For over a hundred years I committed pointless acts of carnage. It's a horribly sad... laughable... and ridiculous story." [78] Prior to being transformed into a demon, Akaza demonstrated superhuman endurance at the age of 11, as he endured 100 consecutive beatings that could make a grown man go numb, thus earning the title of "Demon Child."

Those impressive slashes you inflicted on me... have already healed completely. But what about you? A smashed left eye, shattered ribs and damaged internal organs... all irreparable. If you were a demon, you'd heal in the blink of an eye. Those would be mere scratches to a demon. You can struggle all you want, but a human can never beat a demon."
