Next Scathath Summoning Campaign

I'm looking at JP server's gacha history and I have bad news...
after new year 2017 [n our case: new year 2019 because we're exactly 2 years behind] she was featured only in paid gacha, there was no regular banner with her
I guess on NA the next opportunity will be only on thanksgiving :/
http://fate-go.cirnopedia.org/summon.php#2017 <- JP summon history starting at same moment where we're currently on
http://fate-go.cirnopedia.org/summon_us.php#nav <- NA - scroll up Japan's history to compare banners

From what we know, she only shows up for New Years. She will be in both the paid Gacha and the General New Years Banner for 2020, and 2021.

Though, with how things were this last year, she might be showing up for Thanksgiving instead.
