YEP THAT'S THE SAME HIYORI
WITHOUT A DOUBT
Other similar-looking characters (haven't verified if their names are the same): the guy with a lot of piercings who looks like Kuzuya's friend, the light-haired guy who looks like Kasuya's subordinate, and some random background character who looks like the dad of the guy who has a one-sided, abusive "crush" on Kuzuya
Yeah I love how Harada has a connected universe with some of the Mangas
Same, it makes me feel even more invested in their stories!
I feel like some characters from here appear in Happy Shitty Life. If not, the ones from HSL have to be based on characters from here because they look too similar
