I can tell this is going to be a great novel because usually authors writing novels of this genre don't even bother to write a good prelude. And I also like this author's writing style.
I sincerely hope that this is a story where the mc does what he likes and not another story of the many that already exist where the mc wants to rest but is dragged to fight against everything and save the world
and thus he was reincarnated as the sister to one of the greatest beings in the multiverse. Glory to lord Mongrel!!(U need sauce? Heretics go and read Shadow slave at once!!)
