I personally don't think that any of these are LGBTQ (though Denji does give off aroace vibes) but I can recommend you actual LGBTQ mangas? -Punks Triangle (explicit) -Fated NOT to meet (VERY EXPLICIT) -Marraige Toxin (not explicit) -The Last Passage (no sex scenes but SUPER DEPRESSING) -Maybe Ominiscent Reader's Viewpoint? Depends on your opinion -yeah thats all I could think of)
