It's quite an old manga, that's completed. It's about a travelling man MC that uses talismans with horses (i think) printed on them, and he gets followed by a long haired girl that's really strong, and she follows him because he reminds her of her lover because the man is wearing the lover's hairband - which the MC took from the lover's body after he got eaten by some sand monster. Also MC has a tiny man following him who was basically his servant or something

I can't emember if it was in anthology or not, but it's about this male scientist that got abandoned by his lover in a lab that was doing research on supernatural things, and the beast escaped and killing everyobe. I think it was a huge demon dog/wolf/fox, can't remember, and it shape shifted into the scientist's ex and did him. The ex basically used the uke bait for the demon so they could escape
