I made it because I wanted to paint the backlight with a lasso fill.
(1) Prepare line art and colors

(2) Sandwich a backlight layer between the lineart and the color

(3) Open the folder of the backlight layer and paint the shadow layer with a shadow, and you're done.

②線画と色の間に逆光レイヤーを挟みます

③逆光レイヤーのフォルダーを開いて影レイヤーに影を塗ったら完成です
