I saw this on reddit and got curious.
(edit: Can you see this picture?)

There was a fate school life OVA a few years ago that tied into FGO. Now the servant teaser appeared and the person on the far left seem a lot like a slightly redesigned version of Lei Loi from the OVA. Could this years Collab she based off this manga?
Other people think they saw Arucard in the teaser. Are we getting a Tsukimhime collab? That would be cool but I wonder if Nasu plans to use her in the main story.
The last possibility is a Collab with Mahiou Tsukai no yoru. I'd want a Aoko Aozaki servant in FGO. She has a habit of appearing in type moon stories randomly.
Maybe we are all wrong. What is the best collab event for FGO this year?
