Invisible
It was so fun to watch, but I think it would’ve been even more thrilling if the traitor was someone unexpected, like the old man (I forgot his name) or even Shimura himself. Like, sure, Saruwatari is the Reaper—but what if Shimura turned out to be an even bigger threat? A criminal so dangerous that not even the police, the Reaper, or Invisible himself could uncover his true identity. I bet this twist would’ve made the story even more intense, but even as it is, I really enjoyed it.
