Seiga is her partner or enemy?

What every magical girl anime needs....BOOBS!!!! But she still doesn't fit the useless fanservice character. Someone needs to fill that role.

If I'm interpreting it right, she seems to be "a twisted woman who turned Futo into a magical girl".

ふとちゃんを魔法少女にした謎の悪女せーが
神出鬼没で壁や床に穴を開けて急に出現するゾ！（

別にふとちゃんは下から下着を覗いているわけではない（ぉ

明日はオヤスミ！

Oh and Futo isn't staring at her underpants. If she is wearing any.

Of course we need Big-boobed girls that turned the main character into a magical girl!

In h-doujin I see, Seiga usually play the villain role. Is that because of her Wicked title?
