One idea could be that Akiko is a new ninja in the village and Naruto befriends her. They go on missions together and Naruto helps her overcome her insecurities. For example, on a mission to retrieve a lost scroll, Akiko doubts her abilities but Naruto's confidence in her makes her shine.
Most BSD light novels often have complex characters. Since they are based on literary figures, they bring in the depth and complexity of those original personas. For example, a character might have the same traits as a famous writer but with a unique twist for the BSD universe.
In Naruto fanfiction, Akiko Suzuki could be an original character created by the author. She might be a civilian, a ninja from another village, or even have some special abilities or a unique backstory that ties her into the Naruto universe.
Sadly, I have no idea who wrote the 'akiko graphic novel'. But you could try asking at a local bookstore or library. The staff there might be familiar with it and be able to tell you who the author is. You could also search for it on social media platforms where graphic novel enthusiasts might know the answer.
The appeal of all BSD novels lies in their ability to create immersive worlds. They draw readers in with their unique concepts and engaging storylines. For instance, the way they handle character relationships is very captivating. The conflicts and reconciliations between characters make for a great read.
