I had issues with other Chaton loras, so I made my own. Is it better? I don't know, but it's better for me.

The dataset is very limited and only consists of mostly in-game/promotional art so I can preserve an authentic look.

I don't know how well it generates the gun as most images in the dataset have the gun mostly cropped out. You can try adding gun/weapon tags and such if you want.
