I approve of this style.

I bow to you Keine, for this beautiful gift.

I like this but nothing can beat Imizu's enmaided Mokou

Meido Modo Mokou!

I thought the exact same thing the moment I saw this post.

i thought this was yumeko from the thumbnail

Dialog from the commentary

妹紅「こんな衣装・・・一体どこに隠しといたんだよ」
慧音「ふふ・・・、にゃ～い～しょ♡」
妹紅「な、なぁ・・・慧音、・・・顔から火が出そう///。」

Question, are we sure this is Yumeko cosplay?
