I fear this story will never pull itself out of the poorly set up political conflicts.
MC basically enlisted himself and is meddling heavily as an outsider in an extremely complicated and dangerous power struggle between the "blessed" and everyone else.
Hes playing as an agent inside a political system antithetical to his own goals, because the royalty are somehow reformists, while the greater nobility are conservative.
While its no skin off the royals backs, royals are royals and will always be royals by force of sword and by church - blessings or not, it does effect the balance of power across the entire nation and the legitimacy of radical fringe groups.
As a reader, I have little investment in the state of the kingdom - no matter how "cute" the loli *vomit* princess is. I also cant care about the "dark god squad", it is a band of well trained servants of the princess following the MC around. Once again, very little investment, its just another day in the office for these guys... and for the MC. Their loyalty is to the crown and the princess, they only have a business relationship to the MC and by extension the readers.
Normally you tie stakes to the conflict - give or dangle a valuable thing (family, peace, wealth, "flof") in front of the MC and the reader, compelling them to put their hat in the ring. I see zero reason for the MC to have ever invested himself in this conflict.
The entire story has been derailed because the MC got dragged into a river of "current events" that the reader has no way of ever caring about.
Especially since the exact structure of the conflict is bogus, convoluted and ridiculous. We are following a military unit under the command of a child operating without proper counsel.
Changing the world isn't the express goal of the MC, its kinda a "meh, maybe I will do something". MC isn't "reborn head of a noble house" with responsibility to his subjects, and he isn't an aspiring war lord. We are watching a character choose to participate a battle that he has no stake in for 0 reason other than a loli princess decided to take a shine to him.
