The worst case I've seen was a young adult whose parents still treated him like a child. They wouldn't let him choose his own career path. They forced him into a field they thought was safe. He ended up being very unhappy and resenting his parents.
One of the worst stories I've heard was when a teacher publicly shamed a student in front of the whole class because the student's parents couldn't afford the latest textbook. The teacher made the child stand up and said it was the parents' fault for not providing the necessary materials. It was so cruel and unfair as the family was going through financial difficulties.
This question was not easy to answer because the quality and evaluation of the male lead in the anime depended on many factors such as the plot, character creation, audience preferences, and so on. Moreover, the definition of "the most scum" varied from person to person.
However, if it was referring to the performance of the male lead in a certain anime, then it could be said that every character had its own unique charm and value. It was difficult to simply rate a character as the "worst".
In my opinion, 'High School DxD' had some issues as an anime adaptation of a light novel. While it was popular for its fanservice, it deviated quite a bit from the original light novel in terms of story and character growth in the later seasons. The story started to feel more like an excuse to show off the female characters' bodies rather than focusing on the plot and character development that was in the light novel.
Training for teachers is important. Teachers should be trained to handle different situations and students with various needs. They should know how to respect the family background of students. In cases where there are misunderstandings or bad situations, schools should have a proper mediation system in place. This can help prevent the worst - case scenarios from happening. Also, parents can form groups to advocate for better teaching practices in the school.
Poor pacing is a major reason. For example, if an anime tries to cover too much of the light novel in a short time, it will end up skipping important details. Like in the case of some adaptations where the story feels disjointed as it jumps from one plot point to another without proper transition. This makes it hard for the viewers to follow the story and enjoy it as much as they could have if it was a better adaptation.
"Killing the Crimson Pupils" was a manga and animation with the theme of war and terror. The characters in the series had different endings. But as far as I know, the most tragic ending of the work may be one of the following:
[1 Sebastian Michaeli: He is one of the main characters in the story and a killer with the ability to "cut off the Crimson Pupils".] His ending was very tragic. At the end of the story, he was betrayed by his accomplices, imprisoned in a basement, and finally forced to commit suicide.
2. Julian Chell: He is the other main character in the story, a young soldier. In order to protect his family during the war, he participated in the "Red Eye" project and became an accomplice of Sebastian Michaeli. However, his ending was also very tragic. At the end of the story, he was killed by Sebastian Michaellis and his accomplices.
[3. Arollian Alitti (Alpha Aluminium-Alitti): She is one of Sebastian Michaellis's accomplices and a female assassin with the ability to "cut off the Crimson Pupils".] Her ending was also very tragic. At the end of the story, she was killed by Sebastian Michaellis and his accomplices, and her family was betrayed by Sebastian Michaellis and his accomplices.
The above is just my personal opinion. The ending of other characters may be more tragic, depending on the reader's preference and understanding of the work.
The main difference might be in the art style. The manga could have a more detailed and raw look, while the anime might smooth things out for a better visual experience.
Whether or not the parents in the anime really existed and whether or not they were really dead was not something we could answer. Animation was a fictional art form that presented storylines through exaggeration and imagination. The characters and scenes in the anime were all fictional and had no necessary connection with the real world. Therefore, the family background and experiences of the characters in the anime were not real.
