The Knight Cartoonist and Her Orc Editor, Volume 1

Yeld, an orc sick of life in his dark-fantasy realm, decides to move to Tokyo and become a manga editor. One day, he's visited by a full-time armored swordswoman, part-time aspiring manga artist—one who gets practically suicidal whenever her work gets rejected! Between her, a tentacle monster summoned as an assistant, and a slime girl with all kinds of "helpful" manga tools, there's never been a stranger pack of creators! It's the most realistic(?) depiction of the manga industry yet!
