The term "March" can simply refer the sakura 
season scene (since sakura blooms around that 
time).

The seller will also e-mail more images of the 
merchandise if you specify your e-mail address in 
the Q&A section (that is, if you have a valid YJ 
auction ID).

I have seen a few cels from the game before, so I 
don't believe that this auction is of something 
fabricated.
