... HiMERU-san has stated a prowess in investigations, though everyone seems to have pulled their weight as well. Albedo-san is an alchemist, too. ( so those two are definitely people who should get a heads up, she thinks... had this conversation happened after the island's manifestation, she could cite kaeya and dainsleif personally. ) But I don't believe anyone's found anything like this before. If they have, no one's said anything.
