The booklets from the Fate/stay Night Museum are finally being distributed. Many people on the Japanese fandom already received their copies and they noticed a very interesting detail on Arcueid's profile.
The use of this particular image for Arcueid's Melty Blood section means that Type-Moon is finally acknowledging Mugen as a canon entry of the Melty Blood series. With that in mind, it's quite possible that we could be seeing a Mugen collab event coming along for FGO. With Mugen's vast roster of characters, which ones you believe are the most likely to be making into the game? I personally would like to have Dark Ronald McDonald as the welfare. He should have some really good with Extra Vlad.
