Ok ok, this model may be the original one from genshin impact so it may be from blender or any chinese company because the game creator from genshin is hoyoverse and is chinese so you should check on google and model is not mine srry.
Is this model completely created from scratch in Blender or other software? Or are they VRM based on distributed MMD model data, etc.?
I am studying character modeling and would like to know about the tools you are using.
