I'm not entirely sure as I haven't read it yet, but if it's in line with the previous 'oregairu' works, it might feature Hachiman Hikigaya as one of the main characters.
Typically, in the 'oregairu' series, Hachiman Hikigaya is a central character. So in the 'oregairu new light novel', he is very likely to be one of the main characters again. There may also be other important characters like Yukino Yukinoshita and Yui Yuigahama who often play significant roles in the story and are likely to be main characters in this new installment as well.
Hachiman Hikigaya is a main character. He is a cynical and introverted high school student with a rather pessimistic view of the world and human relationships.
Yukino Yukinoshita is also a main character. She is a beautiful and intelligent girl but has her own set of problems and insecurities. And there is also Yui Yuigahama, who is more of an outgoing and friendly character, often acting as a bridge between Hachiman and Yukino.
Iroha is one of the main characters. She has her own unique personality and plays an important role in the story.
One of the main characters is Hachiman Hikigaya. He is a cynical and introverted high school student.
There may also be other supporting characters that contribute to the story in volume 12. However, without reading it, it's hard to say exactly who else might be prominent. But the three main ones - Hachiman, Yukino and Yui - are likely to be at the heart of the plot, driving the story forward with their actions, decisions and interactions.
The main character, Hachiman, is surely important. His thoughts and actions usually drive the story forward.
Hachiman is a key character. He is a cynical and introverted boy who has a unique way of looking at the world. Yukino is also important. She is a smart and reserved girl. And Yui, who is a cheerful and friendly girl, is another key character.
Yukino is also crucial. She might participate in events with her own style and grace. Her interactions with others during the sports festival add depth to her character. Another important character is Yui. She is likely to be involved in the events with great enthusiasm, and her presence brings a different kind of energy to the sports festival. All of these characters' actions and relationships during the sports festival contribute to the overall story of the light novel.
One major difference is the pacing. The anime might have a faster pacing to fit into the episode format, while the light novel can take its time to develop characters and plotlines in more detail. For example, in the light novel, there could be more in - depth internal monologues of the characters which might be cut short in the anime for the sake of time.
Hachiman is definitely one of the most interesting characters. His cynical and self - deprecating nature makes him stand out. He has this unique view of the world that sets him apart from the other characters. Yukino is also interesting. She is intelligent and reserved but has her own insecurities hidden beneath her cold exterior.
