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, ??????????????, rose head wreath, forehead chain

Outfit: white dress, layered ?????????? 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.
