The gamer aspect can have a significant influence. For instance, if the gamer has certain skills or abilities from the game world, they might use those to deal with the complex relationships in the harem during the pregnancy. Maybe they can analyze the personalities of the harem members like they would analyze game characters and find the best ways to keep harmony.
The OC can be developed by giving him a unique backstory. For example, he could have had a difficult childhood in his own world which led to his love for gaming as an escape. In the RWBY world, this backstory can influence how he reacts to different situations. His skills in gaming can also be further developed, like he starts with basic knowledge but as he faces more challenges in the RWBY world, he learns to adapt and combine his gaming skills with the combat and magic in that world. His relationships with the harem members can also shape his character, as he learns to be more empathetic and responsible towards them.
Often in such fanfictions, the main character, the gamer, is at the center. He might be joined by various female characters from DxD to form the harem. For example, Akeno Himejima could be one of the main characters in the harem. She has her own charm and powers, and her relationship with the gamer would be an important part of the story. And of course, there could be other characters like Koneko Toujou who might also play significant roles, either in the harem or in the overall plot.
One characteristic is the blend of the 'Familiar of Zero' setting with gamer tropes. There are often stats and leveling systems added to the characters. For instance, a character might have a 'charm' stat that affects how they interact within the harem.
One common theme is the power - up. Just like in games, Ichigo often gains new abilities or levels up, which helps him in both the gaming aspects and in winning over his harem. Another theme is the exploration of relationships. Since it's a harem genre, there are multiple love interests, and the story usually focuses on how Ichigo navigates these complex relationships.
I'm not sure specifically as I haven't read it. But generally, a 'gamer' in the title might suggest it involves gaming elements. 'Harem' often means a group of characters (usually female) surrounding the main character in a romantic or close relationship context in fictional stories. And 'web novel' indicates it's a novel published on the web.
One popular one could be 'The Gamer's Harem Adventure'. It often involves a gamer character who, in the fictional world of the story, attracts a group of diverse characters to form a sort of 'harem'.
One common theme is the growth of the gamer oc. As they interact with the members of the harem, they often develop as a character, both in terms of their in - game abilities and their personal relationships. Another theme is the exploration of different personalities within the harem. Each character in the harem usually has a distinct personality, and the fanfic delves into how the oc copes with and relates to them all.
The main character is Naruto. He's the one with the gamer abilities. As for the harem, there are likely to be characters such as Sakura. She's a well - known character from the Naruto series and could be part of the harem in this fanfiction. Hinata might also be there, given her strong feelings for Naruto in the original story. There could also be other female ninja or even non - ninja characters added to the mix to form the harem.
The combination of Ruby, a gamer theme and a harem concept can be really appealing. Ruby has its own unique charm in the world of programming and gaming, and when you add the harem element, which often involves multiple characters with different personalities and relationships, it creates a complex and interesting fictional world.
