I'll be real honest here, I cannot for the life of me see the MC as a future ruler right now. They're generally pathetic, and have very little personality next to their king guards. While there could be some measure of character growth to come for the MC (I don't know how long the game is meant to be), I'd like to see quite a lot of it by the time they destroy this cult and take back the kingdom. Like, I get it, MC is a spoiled royal who's never really had to lift a finger to do anything for themselves before now; but now that shit's gotten real and they're next in line and know the responsibility that's to come, you'd think you'd see them actually trying to really prepare themselves. But instead, their king guard is still doing everything like, as the previous person mentioned, a glorified babysitter of a seven year old. I wish we'd get actual options to shape the MC's personality, and make him less of a bland wuss.
I do REALLY love the three king guards though, and the art (except for that awful Leandros dream scene CG that looks like a weird ripoff of the Disney style - you know the one) is chef's kiss. Ramos is my favourite to date.
