The length of manga one shots can vary a lot. Some might be as short as 20 pages, while others could go up to 80 pages. It really depends on the story and the author's style.
I'd recommend 'Peter Parker's Hidden Talents'. In this one - shot, Peter discovers a new ability that has nothing to do with his spider - powers. It's a really creative take on the character. The story is short but full of interesting twists and turns.
An animated film like Slam Dunk hadn't appeared yet. Slam Dunk was a Japanese manga and animation that told the story of high school basketball. This work caused a huge sensation at the time and had a great impact on the Japanese basketball culture at that time.
Although there were many different types of cartoons in modern times, there were still very few basketball-themed works like Slam Dunk. Some cartoons may have a basketball theme, but they are often very different from the original.
I have no definite answer. Sometimes manga series end when the story feels complete to the creator or when publishing circumstances change. So, we'll just have to wait and see.
No, there isn't. The main emphasis of Haikyuu is on teamwork, friendship, and the pursuit of excellence in volleyball. Love stories are not a significant part of the plot.
The Haikyuu manga is indeed over. It had a great run and left a lasting impression on readers. The story came to a satisfying end, tying up loose ends and giving closure to the characters' arcs.
