Well, SFX in manga are basically the written representations of sounds. They help convey the auditory aspect within the visual medium. For example, 'BOOM' for an explosion or 'ZAP' for an electric shock. They enhance the reader's imagination and make the scenes more vivid.
The JJBA manga is indeed finished. It had a great journey and wrapped up with a satisfying conclusion for fans. However, there's always the possibility of spin-offs or related works in the future.
Well, 'jjba visual novel' is likely related to the 'JoJo's Bizarre Adventure' series in a visual novel format. It probably features the unique characters, their stands, and the wild storylines from the original work. You can expect lots of character interactions, decision - making elements that might affect the story, and of course, the over - the - top and creative art style that the 'JoJo's Bizarre Adventure' is known for.
There's also 'Diamond in the Rough'. This fanfic focuses on a unique relationship between the reader and a JJBA character. The writing style is very descriptive, especially when it comes to the Stand battles. It really brings the action to life and makes you feel like you're in the middle of the chaos.
Some JJBA fanfics that are worth reading are the ones that expand on the battles. They might add more complex strategies or new foes that the characters have to face. For instance, a fanfic could introduce a new stand user who has the power to manipulate time in a different way than Dio. Also, fanfics that give a different perspective on the existing story arcs, like seeing the events of Stardust Crusaders from an enemy's point of view, can be quite engaging.
