Aizawa is still going strong in the manga. There's no event or storyline that has resulted in his death. The creators have chosen to keep him as an active character.
One common theme is his role as a teacher and mentor. Many fanfics explore how he guides and influences his students at UA. Another theme is his mysterious past. Writers often like to uncover bits of his history that are not fully shown in the original work. Also, his relationship with other characters, like his colleagues at UA, is a popular theme.
Aizawa Ryaka was described as a strong, quick-witted female character in " Hot Blood High School 1." Although she has always been seen as the protagonist's ally, she also has complicated relationships with other characters.
The story about Aizawa Ryaka's kidnapping did not specify whether she was kidnapped by Hideto Banto. Although some readers believed that Aizawa Ryaka was forced to join the Hideto Bando organization, other plots and descriptions of the characters also showed that she had her own motives and choices. Therefore, this problem needed to be carefully considered and explored in the plot of the novel.
In the mainstream series, Aizawa is often seen as a tough but fair teacher. However, in the fanfiction, they might exaggerate his negative traits. For instance, his strictness in the original might be turned into extreme rigidity in the fanfiction, making him seem almost unapproachable and not at all understanding of students' difficulties.
One common theme is isolation. Aizawa is often shown isolating himself from others because of his depression. He may push away his friends, students, or colleagues, thinking he's a burden.
One common theme is the discovery of a softer side. Aizawa, who is often seen as a strict and no - nonsense character, shows his more tender and caring side when interacting with the cat.
One common theme is resilience. Aizawa often has to deal with a lot of pain, but he shows great strength in bouncing back. For example, in many fanfictions, he endures physical injuries during battles but still manages to come back stronger.
One common theme is mentorship. Nezu, being the principal, often acts as a mentor to Aizawa in many fics. Another theme is problem - solving. They usually team up to solve issues within UA, whether it's dealing with a difficult student or a threat to the school. Trust is also a big theme, as they have to trust each other's judgment and abilities.
One popular aizawa fanfic is 'Aizawa's Hidden World'. It delves into his past and his relationships within the UA faculty. Another great one is 'Aizawa and the Lost Student' which focuses on his role as a mentor in a rather unique situation. And 'Aizawa's Quiet Strength' shows his character development in different scenarios.
