Call me morbid, but I have always taken a keen interest in looking beyond the facade of any character in hopes of unearthing the darker aspects of their background and personality. That is why I take a perverse liking towards someone like Chihaya whose gloomy disposition can be attributed to certain factors such as a broken family. Of course, she is just one of the more obvious examples, which you can easily deduce just by reading up on their profile.
As mentioned previously, the Futami twins began show business by performing under Ami's name, though in the sequel, the Ami and Mami are their own idols. This has got me wondering if there exists some form of rivalry between the two that could have escalated to deep-seated mutual dislike. For better or worse, the only things I have to go on are pretty just fanart that reflect this sentiment Well, after watching this episode, I have come to realise the fact that I am a rotten person for thinking that Ami and Mami are fighting to be the superior twin. The dynamism of the this pair is really at another level, the way they are always on the same wavelength and are able to come up with impromptu skits - trust the two to turn another episode revolved around a misunderstanding into a full fledged detective noire masterpiece Really, the only depressing thing about Ami and Mami is that they are separated by Ritsuko.
P.S Why is Azusa so fat?
