Ron's genius stays locked behind his eyes, so the real mystery becomes whether he'll actually let Totomaru in. Season 2 stops pretending the cases matter more than the partnership. The deductions are still airtight, but now you're watching to see if a burnt-out prodigy and a cop built for rules can survive knowing each other's worst parts. That's the forbidden thing the title was always talking about: not the detective work, but the vulnerability that comes after trust breaks through someone's walls.

Ron Kamonohashi, once a star at the elite detective academy BLUE until his expulsion, has settled into a working partnership with police officer Totomaru Isshiki, and together they have cracked a string of cases. Their resolve sharpens when they learn that the notorious crime syndicate known as the House of M was behind Ron's removal five years earlier. The group also seems tied to Ron's strange ability that leads to the deaths of people near him, something he badly wants to end. When a House of M member begins a showy series of killings across Shibuya to taunt Ron, the pair must catch the killer while uncovering more about Ron's past and his condition. This second season of the mystery drama is adapted from Akira Amano's manga.
