Yesterday, I came across those pictures on tumblr.
And I found out that they were from Janiben with Kuwabata Ohara on July 27th, 2011. Unfortunately, all the links on dozchan were dead now and nowhere can I find any copy of this episode. Can anyone help me re-upload this ep? I'm really thankful to you for your kindness. Thank you in advance ^^
EDIT: SOLVED! thanks to the great help of emptyspaces0_0 and linh_kc :D
EDIT 2: Anyone who would like to get the link, please check the same post in onlyeitofiles. Sorry for causing such confusion. If needed, please delete this post, mod. Thank you ^^
