To be honest, Takamina-san was an amazing leader, and along with Atchan, the reason they reached Tokyo Dome. I love YokoYama Yui-san, but she doesn't have the same leadership qualities. Takamina-San lead them by being strict, and not putting up with laziness, while YokoYama Yui-San wants to stand with everyone, instead of leading. This, in my opinion, is why AKB48 has fallen to HKT and SKE respectively. AKB48 needs another leader like Takamina, to reach that height again.
If i watch this video a little bit longer i would cry, it was the saddest things to see the senior member of akB48 graduate from the group.Personally for me, seeing one of them leaves the group or organisation was the most painfull moment..( TAT ) one thing for sure, i love them so bad, i bet all of you also loved all AKB48 as much as i am
