Why isn’t Shion a gnosis?
The question that became so irrelevant, even the LP forgot about it.
In Episode 1, it was established that everyone who is touched by a gnosis becomes a gnosis. Also, we got to see Cherenkov, ya know, become a gnosis. Logically, it must only be a matter of time before Shion herself becomes a gnosis, as she was nearly saltified back on the Woglinde before KOS-MOS’s rescue.
And then… it’s never mentioned again.
