It's been a surprise, this series. First we have the light-hearted, stereotypical harem fun for eps 1-15. Then we have a serious plot kicking in at ep 16ish, culminating to the grievous departure of key characters at the later eps. I wonder if it's all going to end. From the preview of the last ep, it looks like yet another heavy ep. Probably Nemu survives, gets her bro and Sakura goes away. And so Sis-con beats Loli-con. Was hoping that ep 25 will pave the path for closure of the series but things just got more complicated. I thought the high point of the ep was when Nemu enlightened Sakura on how alike they are in their selfish love for Mr Onii-san. It was slightly lost in the fansub translation but it should be noted that both Nemu/Sakura emphasized that Sakura/Nemu ONLY, they would not allow to be with Mr Onii-san. (Apparently they don't think much of the other girls) Reason being, they know and feel (being so alike) the extent of love the other has for Mr Onii-san. An overwhelming and flaming love that would incinerate all hope of any other girl who wishes to be in the race...... Interesting insight but I personally find it hard to grasp.
