The short story in Tekken 7 could be due to various reasons. It might be to keep the game fast-paced and action-oriented, or perhaps resources were allocated more towards the graphics and mechanics.
It could be that you rush through the storytelling or don't spend enough time fleshing out characters and settings. Also, lack of diverse events or complications can make the story seem short.
Maybe the brevity was intentional to focus on a specific moment or emotion and make a stronger impact on the readers. Also, the story might have been designed to be a sort of snapshot rather than a detailed account.
It could be that you haven't explored all the possible subplots or character arcs. Also, the lack of descriptive language can make the story seem shorter than it could be.
Music is short on stories perhaps because it aims to communicate in a more abstract and intuitive way. It's about creating a feeling or atmosphere rather than laying out a full-fledged story. Plus, listeners' attention spans for a single musical piece might not be long enough for an elaborate story.
In the original 'Black Clover' series, there are hints of a special connection between Asta and Mimosa. Fanfiction writers expand on these hints, creating unique stories. For example, they might write about how Asta and Mimosa overcome obstacles together, which is very appealing to fans who want to see more of their relationship. Also, the fanfiction gives a chance to explore different scenarios that the original story might not cover, like a romantic adventure or a deep emotional exploration of their bond.
Asta is a very popular character in Black Clover. When you add a gamer - like concept to his story, it becomes even more interesting. People love the idea of seeing his adventures in a world that has game - like elements, such as leveling up, getting new skills in a more video - gamey way.
Since lemon fanfics are inappropriate, we should focus on their general characteristics from the official story. Asta is highly determined and energetic, always striving hard despite his lack of magic initially. Yuno, on the other hand, is more calm and has a natural talent for magic. They both have a strong bond as rivals and friends.
