In most cases, it is legal to watch fanfiction. Fanfiction is generally considered a form of derivative work based on existing intellectual properties. As long as it's not being sold without permission or used in a way that violates copyright in a major way, just reading or watching it for personal enjoyment is usually okay.
Fanfiction.net could also be a place to check. It has been around for a long time and hosts a vast amount of fan - made stories. However, the interface might not be as modern as some other sites. But still, it's worth a shot to search for your desired Dante vs Bayonetta fanfiction.
Asta's leadership style would likely be more energetic and hands - on compared to Yami's. Yami is more laid - back in a way. Asta would probably be running around, getting involved in every aspect of a mission. He'd be the first to jump into battle, leading by example. While Yami gives orders from a more strategic distance.
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.
These two could be from a specific fandom. They are characters that the fanfiction author has chosen to focus on. Michiru's love for Haruka in a tux could be a unique take on their relationship. Maybe they are part of a group of characters in their original story, but here, the fanfiction delves into their individual relationship, with the tuxedo being a significant symbol of attraction for Michiru towards Haruka.
Dante describes Beatrice as an extremely beautiful and pure being. He portrays her with a radiance that seems almost otherworldly. Her beauty is not just physical but also has a spiritual quality that makes her stand out.
Noelle could be a great addition. Her water magic is quite powerful and she has a complex relationship with both Asta and Yuno. She could be a source of both support and conflict in the fanfic. Another good character is Luck. His lightning magic and his rather unpredictable nature can add a lot of action and excitement to the story.
Asta would likely bring a new level of determination to the Crimson Lions. His never - give - up attitude could inspire the team members during tough battles.
