Hi everyone,
So there was definitely a majority in favor of the mom's survival. I apologize to any who felt her death better for the story. If there were concerns that the mc's development will be affected, he believes his mom to be dead, and moreover with the death of his father and clan, he still will develop and grow as a character and person.
Thank you everyone for voting! I'm almost done editing the next chapter for this change in the the plot, and will release the chapter within the hour.
