Spotted in this month issue of the local edition of FHM are not 1 but 3 Shana(s), or rather amateur models dressing up as Shana.
We can easily tell this isn’t quality cosplay since we all know Shana is flat. Seems like this photo shoot is a publicity by Animax as the second season of Shakugan No Shana just premiered not long ago.
Anyway click on the 2 pics for higher res or if you wanna read the article, which has nothing to do with the anime and contains jargon that only locals will understand.
Well if I have to really choose, I will say 2nd pic the one in the centre has the most Shana feel.
