It's now well documented that Mrna poisoning has become a major issue due to the shitty Wuhan virus vaccines, and after thinking about it I have come to the conclusion that if Berserk writer Kentaro Miura took one of those shitty vaccines then it may have been the cause of his unfortunately early death from acute aortic dissection.
Various heart problems have been documented as a result of the vaccine, so it's no stretch that this is the cause.
I personally recommend that his family dig through his medical records to find information so they can add his name to a potential class action lawsuit.
Did he take the vaccine?
This is unknown as said information is unavailable.
We need Japanese speakers to ask the estate this...
