The length of the DBFZ story can be subjective. It includes multiple arcs and character developments, which can make it feel quite lengthy for some players, while others might breeze through it.
Yes, it is. DBFZ Story Mode has many characteristics of a visual novel. It presents the story through a series of visual elements like character illustrations and backgrounds, along with text - based dialogue and narrative, which are typical features of a visual novel.
I don't have the exact number off the top of my head. But you can usually find that information on dedicated gaming wikis or by reaching out to the game's developers or community managers.
Another strong opponent could be Hit. Hit has the ability to manipulate time with his time - skip technique. This would give him an edge against Broly. Broly's brute strength might not be enough when Hit can literally disappear and reappear at will, striking at Broly's weak points during his time - skips.
Issei could be one of Broly's potential friends. Issei is known for his friendly and outgoing nature. He might be intrigued by Broly's power and want to befriend him. Also, Asia could be a friend. She has a kind heart and might reach out to Broly, who could be seen as an outcast due to his strength and different background. Her kindness could break through to Broly.
Well, the length of the DBFZ story in chapters can vary. Sometimes new chapters are added, and it's hard to give a fixed number. Maybe you can search on dedicated fan forums for the latest info.
Since Broly has a rather wild and untamed personality, Naruto could learn to be more in touch with his primal instincts. This doesn't mean Naruto would become a brute, but rather he could find a new balance between his kind - hearted nature and a more aggressive side when necessary. For example, in negotiations or battles, Naruto could be more intimidating. Also, Broly's loyalty to his own beliefs (even if they are sometimes extreme) could inspire Naruto to be more firm in his own ninja way.
