>Mori is a 4channer (I need not explain this)
>She is part of the chadcast
>IRyS is now spouting 4chan terms such as keyboard autist and soundpost
>Fauna has the webm folder and said "lowres mumei my beloved" on stream
>Mumei is orcschizo, while also being the girl who gave the amber hint, while also apologising for that IRyS stream and the mumei split will claim she visits there
Theories
>Mori is an oldfag, Fauna and Mumei started browsing more recently but before they debuted, possibly after auditions (Fauna may have started earlier but is better at hiding her powerlevel or everything old has broken containment to the point where its not 4chan knowledge any longer)
>Mori possibly showed IRyS and Bae 4chan, possibly during the lean incident leading to a misunderstand of what the site was
>During the offcollab arc Fauna and Mumei showed Bae 4chan, since she is a dumb zoomer she believed it was a neo nazi hate machine which caused her to do that salute during the watchalong because she wanted to impress Fauna and Mumei as she assumed they were neo nazis or perhaps thought they just liked edgy humour
>After this stream Fauna and Mumei showed her /vt/ and she realised what this place truly was
>Since bae and IRyS are close Bae showed IRyS and she began browsing which is why she has had 2 containment breaks relatively closely to each other
