Yeah this is a misunderstanding. I'm referring to the smiling shadow itself, not Ichirou haha Maro maro
Yup even those are often used in many manga and anime like Danganronpa and Detective Conan. Since the art style was formerly changed to that of Detective Conan I assume that it is referencing D.Conan
this manga references a lot of 90s manga memes which is used for reactions and the change in artstyle for humorous effect so it's definitely not danganronpa lol
Omg the faces at chapter 5...Am I the only one thinking that it looks like a reference to danganropa?
