Curate, connect, and discover
I'm just rambling now as I'm thinking how equally cursed it was when everyone was turned in stone but after learning that the petrification can fix people's injuries and apparently their illnesses as we saw happen to Tsukasa's little sister, it can also be seen as blessing for those who also were permanently ill or injured so badly that even modern world doctors and experts aren't able to cure or even make the pain much easier for those who need to live with chronic pain and pain attacks or those treatments are so expencive that people can't afford it. The petrification and reviving process could literally perhaps fix even allergies or things like autoimmune disease and that could be seen as a blessing and-
...oh... I actually only now while writing this realized that the first petrification wave and the medusa device could become a subject of being worshipped as a saviour or start a cult in the new world among with people who don't know everything about the petrification device but people would DEFINITELY notice on their own how they are again back to health after being revived and make their own decisions to try to capture the medusa device for themself or when ever people are in need for miracle cure they want and get it to work.
The more people revived, the more likely someone would take it as their life mission to get their hands on working medusa to give cure for people and that power could lead to another interesting plotline if the one doing the good deeds would be someone who just wants people to be in dept for them and own a favor/material for them as a prize for the miracle cure.
I read the word cult and have immediately stamped my approval.
There is guaranteed to be a group of people who worship petrification and the medusa to an almost frightening degree.
