Captive...? ??? ??? ???
-About Claude
It's 100% true, so I can't say anything.
I've had a feeling this was the case, but I can't imagine that in the history of the Aquilegia Imperial Family, from 3,000 years ago until now, there hasn't been a single time when the demonic possession was on the verge of being discovered.
Whether it was the manifestor himself or a third party, anyone who tried to bring the demonic possession of the Imperial Family to light has been eliminated, and the person involved probably died before the curse became uncontrollable... It's because of these factors, in addition to the time limit of the curse's progression, that Claude has committed so many sins.
