Another way to develop the characters is through their relationships with other minor characters. For instance, the OC might make friends with the local innkeeper who gives them advice about the hot springs. Yuuna could have a connection with an old spirit that used to live in the area. These relationships can influence the main characters' development. For example, the advice from the innkeeper might make the OC more determined to help Yuuna, and Yuuna's connection with the old spirit could give her the courage to face her own situation differently.
To develop the OC further, give them a unique backstory. For example, if they are from a far - off land, they could bring different cultural beliefs about spirits and hauntings. This would add depth to their interactions with Yuuna. For Yuuna, explore her past more. Maybe she was once a normal girl who was cursed and turned into a spirit bound to the hot springs. Revealing these details would make her more relatable and complex.
Maybe the OC is a local who has always been curious about the haunted hot springs. Yuuna, on the other hand, is a spirit that is somehow bound to the place. The OC's presence disturbs the normal order of things in the hot springs. Yuuna is initially angry but then realizes that the OC is different from others. They start to communicate, and the OC tries to find a way to free Yuuna from her 'haunted' state, leading to a romantic relationship.
For Flora, you could explore her insecurities more deeply. Maybe she doubts her ability to be a strong partner to Helia in dangerous situations. This could lead to her pushing herself to grow and become more confident.
To develop Roman further, have him mentor Neo in some new skills, like advanced lock - picking or negotiation. This would show his expertise and also his willingness to share knowledge. For Neo, have her interact with other characters outside of Roman. This could make her more well - rounded. When she comes back to Roman, she can share these new experiences, which in turn changes their relationship and helps in character development for both of them.
For David, his overly positive and sometimes naive personality could be developed by having him face some real disappointments. For example, if a camper he really liked left the camp suddenly. This would force him to grow and become more realistic. Gwen, on the other hand, who is often more cynical, could start to open up more when she sees David's unwavering optimism in difficult situations and learn to be more positive herself.
For Alaric, his character could be developed further by exploring his past traumas more deeply. Maybe he has some unresolved issues from his time as a vampire hunter that resurface when he's around Caroline. For Caroline, her character could grow by having her face more complex moral dilemmas. For example, if she has to choose between helping Alaric or following the rules of the vampire community. They could also develop their relationship by having them share more personal stories and secrets with each other.
For Boruto, he could be developed by facing more complex moral dilemmas. For example, having to choose between the safety of the village and the life of a friend who has been misled. Mitsuki, on the other hand, could be developed by exploring his origin more deeply. Maybe he discovers more about his 'parent' Orochimaru and how that affects his identity as a ninja.
Bart's character could be developed by making him more responsible. In the fanfic, Greta could be the catalyst for this change. She could give him tasks to do that are important, like helping her with a community project. As he does these things, he realizes he can be more than just a troublemaker. Greta, on the other hand, could be developed by showing her flaws. Maybe she's overly perfectionist and Bart helps her see that it's okay to make mistakes.
For Ardyn, dig deeper into his emotions. Show his vulnerability when it comes to Aera. Perhaps write about his dreams and nightmares related to her. In terms of Aera, develop her character by showing her influence on the people around her. You can also give her a more active role in the events that unfold, rather than just being a passive love interest. Let her be the one who tries to change Ardyn's fate actively.
Character development could occur through their interactions with other characters. If they meet new androids or humans, how they react can show different sides of their personalities. For instance, if they encounter a human who is prejudiced against androids, RK800 might try to reason with the person, while RK900 could be more defensive. This would show RK800's more diplomatic side and RK900's protective nature.
To develop Art3mis further, the fanfic could explore her backstory more deeply. Maybe show how she got so good at hacking and combat in the OASIS. For Parzival, it could show his growth in dealing with real - world emotions while being in a virtual relationship.
