Another fanfiction idea is to focus on the relationships the character forms because of the smartphone. Since it's a device from another world, it might attract the attention of different groups. Some might be curious, while others could be envious. This could lead to various alliances and rivalries.
Often, the female lead characters tend to be popular. In this fanfiction, if there are female characters who assist the protagonist in his adventures or have their own unique powers and personalities, they can gain a large following. For example, a female mage who helps the protagonist understand the magic system in the new world could be very popular.
The main character is Touya Mochizuki. He is the one who gets reincarnated into the new world with his smartphone. There are also other important characters like Elze Silhoueska and Linze Silhoueska, two sisters who become friends with Touya.
The main character is Touya Mochizuki. He is a normal high - school student who is accidentally killed by God and then reincarnated in another world with his smartphone. He has various abilities and uses his smartphone to his advantage in the new world.
There's also Elze Silhoueska. She is a swordswoman and becomes one of Touya's companions in the new world. She is strong - willed and often joins Touya in his adventures. Another important character is Linze Silhoueska, Elze's sister. Linze is more of a magic user and she also plays a significant role in the story as part of Touya's group.
Touya is really interesting. He's the main character and his ability to adapt to the new world while using his smartphone is cool. Then there are the various female characters like Linze and Elze. They have different personalities and skills, and their interactions with Touya are fun to read.
