Can anyone guess who the green_haired girl in this picture is? The artist didn't identify her in Pixiv.

Chinadress, red eyes, and green hair make me think Ranka.

Well, Ranka has an ahoge, while this girl doesn't.

99% sure its Ranka.

Well you fail at that 1% because: no Ranka tag, no Macross F tag => Isn't Ranka.

The source only confirms that two of these people are Nagisa and Patchy. Let's leave it that way here too.
Probably is what rccompton say, an OC or similar.

Although it seems the green-haired girl looks closest to Yuuka, I second you; let's leave the green-haired girl unidentified. Like I already said, the artist never identified her anyway.

Cute Nagisa, cute Patchouli, and a cute unknown girl. Very nice art.
