Anytime Takenaka is off screen we should be wondering "Where is Takenaka?" because aside from him and now Komaru with her new sense of confidence and maturity the other two characters are kinda floundering. Tanuki has always been pretty flat but Mochizuki still has potential and hidden depths to explore so I pray she gets a characterization boost like Komaru did soon. Takenaka is perfect, he doesn't need to change since his purpose seems to be to change the characters around him.
So does she live alone? Only child? Single working parent? Lives with grandparents? The mystery of her obsession with "perfect families" looks to be soon revealed, maybe...
Hopefully she doesn't have a serial killer bedroom.
