I think it's funny how Sakuya is smiling at her work. Should she really be happy about having two people nodding of at the gate and not guarding it...?
I think I can see what gonna happen in the next episode.Sakuya suddenly remembered that what Meiling is doing now is neglecting her work,and throw knifes at Meiling as usual,AND,she end up throw knifes at Yukari instinctly as well.
