One reason could be for getting attention. People might create a wild story just to be noticed.
I'm not sure specifically what the 'not real plane lady story' is about as it's not a common well - known story. It could be some fictional tale related to a lady and a plane in a made - up scenario.
Most of the so - called 'boys naked on the plane stories' are likely to be false or extremely exaggerated. Airplanes are public spaces with a set of regulations. It is unthinkable for a boy to be naked without a very serious reason. For example, if a boy had a severe allergic reaction that caused his skin to swell and the clothes were too tight and constricting, in an emergency, the crew might have to remove the clothes to help him. But this is a very unlikely scenario in the normal operation of an airline.
In some cases, it could be a part of a unique world - building concept. If the anime is set in a world where magic or some strange phenomenon can turn people into different forms, a girl turning into a baby - like form with a diaper could be just one aspect of that strange and interesting world. It can add a touch of quirkiness to the overall setting of the anime.
Perhaps it started as a joke among a group of people. They made up this story about the 'plane lady' and then it somehow leaked out to a wider audience. Another possibility is that it was part of a creative writing exercise that got misconstrued as a real event.
One reason could be the tiger's territoriality. If the lady entered the tiger's territory, it might attack to defend it.
There's no way to tell for sure without more information. It could be a fictional story that someone made up for entertainment purposes.
One reason could be financial problems. For example, if a family can't afford the school fees, the student may have to dropout. Another reason is lack of interest. When students don't find the curriculum engaging, they might lose motivation and drop out.
One possible reason could be suspicion of criminal activity. For example, if someone is seen near the scene of a crime and fits the general description of a suspect, they might be detainted.
Possible reasons in the 'Missing at 17' real story include mental health issues. A 17 - year - old struggling with depression or anxiety might decide to disappear as a way to escape their internal turmoil. Also, it could be due to a relationship gone wrong. If they had a bad breakup or were in an abusive relationship, they might run away. Additionally, it could be related to educational stress. Failing grades or pressure to perform well in school could push them to leave.
Some people might create such fanfiction for shock value. They want to stand out by coming up with the most extreme and unexpected ideas. It could also be a form of exploring the 'dark side' of a character, taking a well - loved hero like Naruto and twisting his character into something completely unrecognizable. Another reason could be that the writer has a very different and perhaps warped view of the Naruto universe and wants to express that through this very abnormal concept.
