While the beginning of the story was slightly confusing (but that may just be the way my brain works in the morning), the writing became much more clear when the MC left the house. I love the idea for the story, I truly do. It feels rather unique, and I’m excited to see how it develops!
Also, here are some grammatical suggestions. I’m not saying these are all mistakes, but I think these changes could make certain sentences easier to follow.
Whether you believe that the Gods will receive him in the celestial dimension or not, (…) > Whether or not you believe (…)
(…) passed down by his family (…) > (…) passed down in his family (…)
You have not a horse to carry you (…) > You don’t have a horse to carry you (…)
They say “good luck!”, (…) > They wish you good luck, (…)
Keep up the good work!
