Who do those hands belong to? I'm fervently trying to figure it out, but I can't think of a single character that has plain black fingerless gloves like this, especially out of common ships or sensible connections.

Stelle's gloves cover the fingers, Caelus' are too ornamental, Ruan Mei's gloves are a wrong color and cover the fingers, Blade's one hand has "fingered" gloves and one has bandages, Dan Heng's normal form's bracer is too ornamental and he's only got one; and his IL form's gloves have those rings at the end, Kafka's gloves are purple (and cover the fingers), Silver Wolf's are looser and have a bit of blue, Jing Yuan's are bridal gauntlets, Jingliu's are brown and cover the fingers...
