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.
Maybe in the Squalo back story, his relationships also play important roles. His interactions with other members of the Varia could be a key part. For example, how he competed or cooperated with them. These relationships might have influenced his development and actions throughout the story.
Another possibility is that Squalo is a character from a local or less - known story. Without more details, it's difficult to fully explain the back story. It could be a name in a fantasy novel where Squalo is a hero or a villain, with a back story involving magic, quests, and personal growth or downfall.
One interesting 'Harry Potter Squalo' fanfiction could be one where Squalo is introduced into the Hogwarts world and has to adapt to the magic there. Maybe he becomes a student and tries to learn spells, which would be a really fun and unique take on the Harry Potter universe.
I've read one where Squalo is a transfer student to Hogwarts. He brings his own unique fighting skills and a different kind of magic knowledge. It's really interesting to see how he interacts with the other students like Harry, Hermione, and Ron. He gets into all sorts of adventures and even helps in a big battle against a group of dark wizards that were trying to take over the school.
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.
