Another concept is the use of game - like quests in the fanfiction. Instead of the normal tasks in Danmachi, the characters are given specific, often time - limited quests with rewards. These quests could range from rescuing a group of trapped adventurers in a dungeon to finding a rare item for a mysterious NPC. It adds a new layer of structure and motivation to the story.
Bell Cranel is likely to be one of the most popular characters. He is a central figure in 'danmachi' and in a 'gamer' fanfic, his journey of growth and development could be even more exciting as he might level up and gain new abilities in unique ways. Another popular character could be Hestia. Her relationship with Bell is a big part of 'danmachi' and in a fanfic with gamer elements, she could play an important role in helping Bell navigate the new 'gamer - like' world.
One interesting aspect could be the unique crossovers it might have. Since it combines 'danmachi' with 'gamer' elements, there could be really cool scenarios where the characters from 'danmachi' experience gaming - like situations, such as leveling up in a more literal sense as in a game. Another aspect is the potential for new character developments. Fanfics often explore different sides of existing characters, and this one might show how the 'danmachi' characters adapt to gamer - like rules and mechanics.
Hestia is also frequently seen. Her relationship with Bell can be explored further in the context of the 'gamer' fanfiction. Maybe she has some special powers or knowledge related to the 'gamer' elements, like being able to access a hidden 'goddess' shop where she can buy rare items for Bell at a discounted price.
Well, Bell is obviously one of the most popular. He's the main character in the original series and in the fanfiction, his growth and adventures are always the focus. People like to read about how he overcomes new challenges in the game - like setting.
Another concept might be the introduction of new characters through the fanfiction's game - like world. Maybe a character who is a master strategist in the game and teams up with Bell. They could have different playstyles that complement each other, adding a new dynamic to Bell's adventures.
