Something that I have noted is that when Ayano answers to her mother on the phone, she gets into actress mode.
Yes, it's a scheme to make her agree to letting Fumi in, but in retrospect it's incredibly scary that she could do that with her closest relative.
That kid is broken.
I mean... I know some otaku who:
Got into soccer after watching captain tsubasa
Got into basketball after watching slam dunk
Got into cooking after watching yakitate japan
Got into go after watching hikaru no go
Learned to play mahjong after watching the legend of koizumi
So yes, an otaku going...
