In Highschool DxD fanfiction, characters might watch various things. For example, they could watch magical battles between different factions. Since the world of Highschool DxD is filled with devils, angels, and other supernatural beings, these battles can be quite spectacular. They may also watch training sessions of powerful fighters, learning new techniques and strategies. Another possibility is that they watch cultural events specific to their different species, like a devil's ball or an angel's ceremony, which can help them understand the traditions and values of each group.
Well, it depends. The Highschool DxD novel contains some elements such as fan - service, which might not be appropriate for very young readers. It also has some complex themes and battles that might be a bit hard for really young minds to understand.
