Well from what it shows on the sketch If I am 
looking correctly... It has #6 I looked last 
evening through Episode 6 but found no scene 
matching this.. The background is different 
shades of blue Darker at top and lighter down to 
bottom of page. So it's possible.. I am curious 
as to WHY it was numbered like this.. Maybe part 
of the number came off sketch you think...?? I 
will have to look thought the Momiji /memory 
episodes and see what I find.. 

I will load the background as soon as I get back 
from Girl scouts with kids ^_^ got to leave now 
but I will be back shortly. Thank you for trying 
to help!
