Shidou and Masamune's are friends, but Shidou has a misconception of Masamune by thinking that Masamune is homosexual. Shidou thinks this because of how close Masamune and Eromanga-sensei are, thinking that Eromanga-sensei is a man.

It is likely that he likes Muramasa which is shown when he said that he would like to go out with her and her reading a book happily made him happy too, but it most likely will not work out because of Muramasa's interest in Masamune.
