今回は同じ高校の瑠衣とまどかがエンカウント♪

まどかのクラスメイトとして #メガミデバイスが制服姿で初登場😲

これは瑠衣じゃなくても笑っちゃう！

ぜひプラモデルで再現してみてね🎨

登場メガミは赤ずきん、アリス、バレットナイツの二人ですよ～

They included some characters from a different Kotobukiya product line, Megami Device, as Madoka's classmates. I am not familiar with Megami Device, so I had to look at the product catalog to verify who they were.

The grey-haired girl is "Chaos & Pretty LITTLE RED":

The pink haired one is "Bullet Knights Executioner":

The blonde with the bunny ears in the back is "Chaos & Pretty ALICE":

The blonde with the hair bun in the foreground is "Bullet Knights Exorcist", in an alternate color version ("Widow") with blonde instead of purple hair:
