I don't know what that means
tl;dr I'd love a tale of someone like Guts being royally screwed over by fate, curses or demonic pacts, especially if they were of his own making/fault/choice. The inclusion of artifact makes you wonder what kinda artifact it was. But when suddenly there is literal deus ex machina and goddess appears and saves their ass it's not so interesting to me. Then the war of immortals? What's the point of immortals fighting they can't die. Are they all shooting each other into space?
The grammar is fine tho. I'm sure someone would check it out based on the synopsis. But not me.
