Dasu's story certainly not really nice TBH. She works really hard with the Guigui+fisher character to get to front line, get into senbatsu, dropped, coming back, while still sidelined. As for Momoka, I think Sasshi's early character fits her. I don't know why but looking at Momoka and Maria reminds me of Sasshi in early AKBingo. If they can and get the chance to polish their talking and variety skills, they can go a long way.
