Kunimitsu Shidou

Shidou is friendly, straightforward and comparatively relaxed around other authors. Although he competes professionally with Masamune, he does not treat that competition as a reason for personal hostility.

He occasionally misreads the relationships between people around him, leading him to draw incorrect conclusions about Masamune and Eromanga-sensei.

Shidou also takes an interest in Muramasa and is pleased simply to see her enjoying a book, although she does not reciprocate his attention in the same way.

Shidou has no supernatural abilities. He is a professional author capable of producing work competitive enough to place highly in a publishing contest.

His writing earns third place in the competition involving Masamune and Muramasa, resulting in publication of his work.

Shidou is introduced during the novel competition that brings Masamune Izumi into direct professional conflict with Muramasa Senju.

He submits his own manuscript and ultimately places third, securing publication.

Shidou subsequently remains part of the broader author community surrounding Masamune rather than disappearing after the contest.

Masamune Izumi is Shidou's fellow author and friend despite their professional competition.

Muramasa Senju attracts Shidou's romantic interest, although her own attention is directed elsewhere.

Ayame Kagurazaka works within the publishing environment handling the authors involved in the competition.
