This one just felt so "anime-ish". Even if it meant to reference some mythology or historical shit, the concept is so FGO kind of thing. It's so out of place....
At least twice... And now already activated three times.... We thought we survived 2020, but in reality this is 2070 but they make us think this is 2021...
Wait, is it lethal though? Like what the people down below said about the Nuclear stuff. If his purpose is only to "scare" people without actually killing them then i don't think it's that much of a danger. But it is pretty annoying and troublesome.
That's... Kinda smart concept, but kinda messy. The only thing required to not killed by it is to simply acknowledge it right? Why don't just share the information about it? Why not try it on other Keter class SCP first to annihilate them? This one is kinda badly written, i feel like it's exist...
What if you order her to "destroy the universe and proceed to kill yourself"?
Sidenote: This SCP remind me of the character from Hunter X Hunter, Killua little sister or "Something(Nanika)" that can grant any wish with equal sacrifice.
