Quick question! I know that Zazie is a guy, especially in the anime, but is he a girl in the manga? It keeps saying "she" when it refers to him.

oh, so あなた notice that, satsuki-chan? Well, it can be simply explained like this: "Due to a translation mistake in the early scanlations of the manga, Zazie had been confused to be a girl. However, he is now confirmed to be male." - this's what the Admin explains :))

So don't worry, Zazie is a male for sure, both in アニメ and manga. Just a little mistake messed his gender up a bit ^^ Later, it has been fixed!

Keep watching and 読書 Tegami Bachi, sweetie!!! Glad that あなた 愛 it now! :D
