Curiously Rei was only worried about Pencilgon. Does she know Oikatzo’s player is male?

It’s kind of obvious by the way that he speaks, calling Sunraku “omae” and stuff like this, he talks like a man even if he got a girl as avatar. Psyger-0 kind of avoids outing her RL gender by speaking only the bare minimum (also because she’s rather shy), but it seems that Pencilgon knows that she’s a woman because she called her Psyger-chan.
