Obviously the hand below is from the OP
The most noticeable part of the hand is the finger nails. It is rather long.
Now its Nanaly's hand
Notice that she has short finger nail, thus can't be the one in the OP..
Let's see further; if its not nanaly's, whose else can it be.
CC's hand
She has a long finger nail and also one who know about Lulu's geass... One of the most likely candidates.
Kalen's hand:
It surprise me that her finger nail is not long; thus its unlikely to be her.
People which I think have long nail; (but no screenshot)
- Euphie
It can be her; although I don't think its her hand since on the next screen of the OP, she is standing next to susaku
- Miley
Its unlikely to be her..... very unlikely..
- Nina
VERY VERY VERY unlikely.... do I even need to say why?
- Shirley
It can also be her, she has a thing for Lulu, thus reaching out for him wouldn't be strange.
I do not have a clear pic of her hand. She is rarely on the screen, let alone seeing her hand up close -_-
This is what I got
Assume that the hand is drawn correctly, she doesn't have a long finger nail... thus is unlikely to be the girl in the picture.
Sakuya (or I think that's her name)
Since we do not have screenshot of her 'hand' yet. Can't really make any comparison. But she can be a very good candidate..
