On the topic of the soul-binding, I'm of the firm belief they need to have a feature/way to undo it for when more options come out. Simply by virtue of the way the game is being developed, if you choose to bind your soul to Keros now because you are curious about the content, it will screw you over later when other options with new content come out. Also, I hope future options mean more than the Kitsune one. I get that the biggest changes would be in the fox-den by nature of the transformation and how Keros as a god is, but it seems like you being a Kitsune or the Champion of a God isn't even acknowledged anywhere else in the game.
Or maybe overtake Keros by repeated pregnancies(?) thus making "her" more weaker and weaker to the point that you can "apropiate" her deity status by fucking "her". Dunno, it could be a good way to "corrupt" the Kitsune village by fucking her deity out of existance
"As the end. You snuffed Keros of her station, Kiyoko amused stares what it once was her patron deity while her; with the memories of a true god she asks you
"my beloved, you wish to take my people's position as a god of the Kitsune with me?" Tempting as she elaborates you think the posibilities. From one part you can teach those bastards what a ruler can be and due your station have nothing. But obey, on the other hand you could free them by making "souls". monikers of something they could never have. Giving them the curse of free will to wander Savarra forever without knowing what the future will have to them. Godless...Unguided..."
>If overtake Keros
"Your thinking is perverse. Yet a good course of action. You decide to take her offer, She mantles you asthe new August master at the center of the world. Divine ruler of the Kitsune and the maximum authority of them alongside your Fox-wife. Elevate your bloodline as divines. Kinu. At first doesn't take it well. But after a short time she likes being respected and feared by the nobles from the Old Country. You become a God-like entity favouring the honored warriors, and punishing the deviants that defies your position along side your wife a true Goddess."*
>Corruption choice
"You decide to enact your vengeance of those who dared to make you less, You explain your plan to your wife. She at first looks horrified, then she aquieces recognizing that you have been wronged; "
Go ahead, they deserved it those whom looked and frowned upon you needs to be disciplined then I have no complaints." You decide your first victim:
Nakano, He could be a good experiment to know the extension of the powers that once had Keros. Then you procede with your vengence*"
Dunno It could be a good way to flip the bird to Sperg McGoo
