It's time we actually lay out who is or isn't involved in this mess. I watch and enjoy NijiEN quite a lot and even I'm tired of this shit. But maybe we should determine who actually is a part of this bullshit.
Categorizing them by their involvement...

The E(vil)nna Clique Confirmed members
>Enna
>Kyo
>Millie

Extremely Likely involved (Practically a member)
>Uki
>Luca

Highly involved
>Aster

Medium/Likely involved
>Vox
>Nina
>Reimu
>Shu
>Fulgur (his one defence is he talks to practically everyone)
>Hex
>Ver
>Finana
>Scarle
>Ren

Little to no involvement
>Pomu
>Rosemi
>Selen (Contention against her is she communicates with almost everyone)
>Elira ("The cause of it all", but strongly disconnected from any of the current events)
>Ike
>Mysta (in fact, reacted the most violently against being in the GC stream)
>Alban (Hangs out with World/JP more than EN at this point)
>Meloco
>Kotoka
>Ver
>Sonny
>Aia
>Petra
>Rosemi

Other nijis are welcome to correct me if I'm off on some/others.
