A conversation between the two:

ＱＢ「僕と契約して魔法少女になってよ」
秀吉「ワシは男じゃぞ？」
ＱＢ「え？君の性別は秀吉でしょ？

QB: Make a contract with me and become a magical girl.
Hideyoshi: Aren't I a boy?
QB: Eh? Your gender is Hideyoshi?

''Take me to your sister'' works the same way too.

Slightly revised translation:

ＱＢ「え？君の性別は秀吉でしょ？

QB: "Make a contract with me and become a Magical Girl!"
Hideyoshi: "I'm a boy, you know."
QB: "Eh? Your gender is 'Hideyoshi', isn't it?"
