I'm honestly of the opinion that Delling Rembran is an idiot
Like the only reason he's alive is because Suletta beat Guel before Vim's assassin took him out
How do you put in place a system of inheritance, like he set up for Miorine and Asticassia and not set up safeguards to ensure that no one kills you so they can stop the duels early and still gain the power they desired? Like that is piss poor planning right there and would have been his own fault in many ways as really, that a shrewd business decision at that point for Vim to make as it ensured his son would remain Miorine's fiance, would stop the duels, and would ensure he immediately took over the Benerit Group
That's like win-win-win for him with very little drawbacks and that would have been the case for whoever was the backing behind the current holder at any given time, so Delling should have set up safeguards like "If I die before Miorine turns 17 the results of all Holder duels are null and void" and/or "If it is even suspected that the company backing the Holder had any role in my death they are automatically disqualified as Holder" etc.
But either Delling had a bit of a death wish (which is possible, but I think unlikely) or he really thought so highly of himself that he thought such things unnecessary (very possible, but not indicated in canon) or he just straight up didn't even consider it (most likely given what we are presented with in canon but makes him look incredibly dumb)
