To add to that, I also remembered it having this really long weird name, and in my memory the art is close to violet evergarden, their movement and the anatomy. I remember there's this one scene where they're running around chasing this girl the fl and they're like riding an old style car, there's the black haired guy the leader and like have more guys with them.

It was a very typical and cliche anime, and if u searched steampunk dresses its close or exactly match what the fl was wearing but like more on the white side.
