I'll still cheer for Erika and Takashima, only because Takashima actually being honest with her regarding her guilty pleasure, as opposed to Misato who was shown to adores Takashima as her Goddess, Erika sees Takashima more like a rival (she actually have a crush on her), and treat her as a person of similar stature.
I wonder why Takashima seems guilty about Misato though.
Eitherway, upcoming love triangle?
This gonna be good.
Also seems like Erika is fully dropping the tsun and goes all dere and nice mode to Takashima, which is nice. I wonder how she will react when Misato arrives.
