I'm not entirely sure as I haven't read it in detail. But generally, a light novel often involves various elements like character development, a unique plot, and perhaps themes related to youth, friendship, or personal growth. It might be about a story set in a world where music plays an important role, given the 'orchestra' in the title.
Since it's an orchestra - centered light novel, there might be a talented young musician as one of the main characters. This could be someone who is new to the orchestra and has to learn to fit in. There could also be an older, more experienced member who acts as a mentor to the younger ones. Another possible main character could be someone who has a special connection to the orchestra, like a person who founded it or someone whose family has a long - standing relationship with the orchestra.
Trans-Siberian Orchestra was formed to create a unique blend of rock and classical music with a focus on elaborate stage shows and holiday-themed performances. Their music often tells emotional and epic tales.
It could be a story about a passionate individual who finds joy and meaning in the precise art of orchestra tuning. Maybe he has a unique journey related to it.
He wasn't sure. The information I know about the source and background of the Ao Ao awaiting arrest comic is very limited. It could be adapted from a novel or an original. If you can provide more information about the manga, I will try my best to answer your questions.
