Assuming that Elira's clique is in power via monopolizing what is translated to high management, where do the other livers fluent in Japanese fall in the clique to where they wouldn't feel like threats?

My Theory:

Petra - Non confrontational, isn't high in power but doesn't fight against it, enabler

Shu - Elira nepohire, likely under or equal to Millie and Enna, that or an enabler

Ike - Mystery, perhaps blackmailed into silence (sexpest allegations), enabler

Sonny - Mystery, perhaps blackmailed into silence (PL shenanigans), enabler

Yugo - Terminated

Zaion - Terminated

Kotoka - Basically JP, likely removed from situation

Meloco - Basically JP, likely removed from situation
