I remember reading manga, and she was the cutest character for me. I'm thinking about also making protagonist from the anime, but I think it'll be worth waiting a few more episodes...
Weight - 0.8-1 (mostly 0.8)
Apperance: originil, blonde hair, very long hair, hair bun, braid, red eyes, medium breasts, rose head wreath, forehead chain
Outfit: white dress, layered dress, off shoulder dress, strapless, long sleeves, navel cutout
Minor tips:
I tried to make her wristband or whatewer it is, but it not working well, you can add "jewelled wristband" if you want to try. There may be minor issues with the dress's structure for certain poses. Because the dress's structure, by definition, won't allow for these poses to be executed correctly.
