Arifureta Shokugyou de Sekai Saikyou (WN) - Chapter 384

This is a rebirth story of a normal girl, Kylie. She was a normal girl, living a normal life. Married and had kids. Nothing outstanding about her, but nothing terrible either. Then she was attacked and left to die.

Her soul screamed in pain at having to leave behind two small children that needed her, yet she couldn't do anything. As she entered eternal darkness ... it took her some time to realise that she was not dead. She was alive, only yet to be born.

And she was a boy.

This is a story of a little man who walks forward silently, in awe, and strives to chase his dream.
