Any horror manga with fucked up twist specifically like monkey peak the horror was good and the twist of the (Spoiler) hiker siblings was so fucked but it was interesting and the author didnt try to romanticize it —they just showed it how it was.Dont get me wrong im not “into” that type of stuff i just like dark themes or dark fantasy ?
Or any horror manga in general that is actually scary or weird but like good weird (=・ω・=)
