One possible reaction in a fanfiction could be about the new dragon species introduced. A character might be in awe, thinking 'These dragons are so unique! Their colors and abilities are like nothing I've ever seen in Berk.'
Well, Mugen Visual Novel is a concept that fuses two different things. Visual novels are known for their story - driven gameplay, with lots of text, choices, and different story paths. Mugen, on the other hand, has been associated with creating custom fighting game content. In a Mugen Visual Novel, perhaps you could have a story where the outcome is affected by fighting elements. For example, characters might battle to progress the story, or their fighting abilities could be part of their character development in the narrative.
Hiccup would likely approach it with enthusiasm. Since he loves his dragons and his adventures, he would be eager to see how others imagine the world of 'How to Train Your Dragon'. He might find some fanfictions that give him new perspectives on his own life and relationships. Toothless, being a dragon, might not understand all the words but would react to the emotions in the stories. If the fanfiction shows a happy moment between him and Hiccup, he might get excited and start making his little happy dragon noises. Astrid would probably analyze the fanfiction carefully. She would look for any inaccuracies in how her character is portrayed, especially when it comes to her skills as a dragon rider and her relationship with Hiccup.
A key feature of mugen games with story is the character development. Since there are often a large number of characters from different sources, the story allows for their growth and evolution. Another feature is the plot progression. There's usually a main goal or conflict that drives the story forward, like in "Mugen Souls" where Chou - Chou's quest to rule the multiverse is the central plot. Also, the story can add replayability as players may want to experience different story paths or outcomes.
Well, without knowing the details, it could be special because it's someone's first story. First attempts often carry a sense of rawness and authenticity that can be really appealing.
I'm not very familiar with the specific 'Mugen Kung Fu Man' story. It might be a relatively niche or new creation. Maybe it's about a kung fu master in a fictional world named Mugen who has extraordinary martial arts skills and embarks on various adventures to fight against evil or pursue the highest level of kung fu.
