This is is the special from one of the volumes. Credits to the original scanner. I do not know who scanned it unfortunately.
I do not know which volume is this from. Those who know, please tell me.
All 3 specials are now completed. Those who are interested in the Volume 25 and 26 specials, they are also on my blog.
