【うちの子】魔黒ルークちゃん（線画）/ Rook-chan (Lineart) (Pixiv Fanbox)

Sorry for the wait, the lineart's pretty much done! I still get the feeling I could do more, but I know I already spent a lot of time working on this, so I'll probably just do the extra details when coloring, and attempt at adding the belly realm as the background.
