It's a graphic novel related to the 'Case Closed' series. Usually, it involves detective stories, with the main character solving various mysteries. It might have cool illustrations to go along with the exciting plots.
The term 'case closed' makes me think of the well - known anime. However, 'child ran' seems rather ambiguous. As for 'fanfic', it implies that it's a fictional work created by a fan. It could be that in this fan - created story for 'Case Closed', there is a plotline involving a child running. Maybe it's a key event that drives the story forward, but again, without more details, it's difficult to be certain.
It might be nonfiction. Sometimes real-life cases are presented this way for educational or documentary purposes. However, without more context, it's hard to be sure.
One interesting aspect is the creativity it allows. With original characters (OCs) in the 'Case Closed' universe, fans can explore new storylines that the original series might not have covered. For example, creating an OC detective who has a unique approach to solving cases.
First, know the 'Case Closed' universe well. This means being familiar with the characters, the setting, and the general style of the show. For example, understand how Conan solves cases and the personalities of other main characters.
The 'case closed' part gives us a hint that it might be related to the world of the 'Case Closed' franchise. A fanfic writer might have come up with a story where a child runs, which could be the start of an adventure or a part of a larger plot. It could involve the characters from 'Case Closed' interacting with this running child, and there could be a mystery to solve, or it could be a more character - driven story focusing on the child's journey. However, without reading the actual fanfic, we can only guess at what it's really about.
You could also swap the roles of the Black Organization members. For example, Gin could be the one who is secretly trying to undermine the organization from the inside, while someone like Vodka is in a more powerful position. This would completely change the dynamics of the whole 'Case Closed' underworld plot.
