Best example of that is the dude who can travel through time. She runs up to him in the middle of the night and suddenly decides she trusts him enough to tell him that her classmate got killed right in front of her. Anyone with half a brain cell would immediately think, "Why would she hide this CRITICAL information until this very moment? If she didn't trust me earlier, she should have gathered more people and told everyone in the classroom. That would be the most sensible thing to do right? So why is she doing something completely irrational and incredibly dangerous? Could she have been so traumatized that she couldn't say anything about her classmate being devoured? Wait that doesn't make any sense, she said they went their separate ways. And wasn't she a bit too calm and acting a bit too normal after her classmate was murdered? She's only a middle schooler, just like me, how on Earth can she not focus on the fact that someone was murdered right in front of her? Not to mention, it doesn't make sense that she could escape unscathed. The boy who died only had the power to nullify other talents. What could he do against a monster like that? Something isn't adding up!" Even if the time traveler didn't factor in that Nanao probably couldn't hold a monster off, there are still ample danger signs. The fact that he is so incredibly stupid is what makes her plan work. That's why this is poorly written. Everything magically works out in Nana's favor, because EVERYONE is stupid. That's why it's incredibly boring and lazily written. It's not a problem that children are getting tricked, it's that they act like middle schoolers are complete fucking idiots beyond human measure. I can believe them missing out on one obvious danger sign, but THEY ARE COMPLETELY FUCKING OBLIVIOUS. That's simply uncreative and lazy writing. Stories where the MC just has ridiculous levels of plot armor are boring. I can also go through the scenes with the knockoff L, where he doesn't expose her identity when he easily could, but I think I got my point across with this one. Please explain how it is entertaining to watch dogs get tricked by a normal human who cannot fabricate a decent false narrative, but gets away with it because the dogs have 0 brain cells?
