For the characters in Vampire Knight in a 7 Minutes in Heaven scenario, their personalities can develop in various ways. Take Aidou for instance. He is usually flamboyant and carefree. But if he is paired with a serious character, he might have to tone down his antics and show a more mature side. Ruka, who is often jealous and possessive, could learn to be more selfless if she is paired with someone who needs her help. This would be a big step in her character development. Also, for the human characters, like Yori, if she is paired with a vampire, her fearlessness or her ability to adapt can be developed as she tries to handle the situation with the vampire during those 7 minutes.
In the 7 Minutes in Heaven setting, characters' personalities can be developed through the forced one - on - one interactions. For example, Yuki's kind - hearted nature can be further explored if she is paired with a difficult character. She might try to understand their pain and in doing so, her own empathy grows. Kaname, being the brooding and powerful vampire, could show a more vulnerable side if paired with someone he truly cares about. He may let his guard down during those 7 minutes and reveal his insecurities. Zero, with his tough exterior, might soften a bit if he is paired with a character who sees through his facade and makes him confront his true emotions.
For Yuki, she could be dressed as an angel. It represents her pure - hearted nature and her role as a mediator between the humans and vampires. The white dress and wings would symbolize her hope for peace and harmony at the academy.
One idea could be that a character from the Vampire Knight world gets paired with an unexpected person in the 7 Minutes in Heaven game. For example, Yuki could be paired with a lower - class vampire. This would create an opportunity for them to have a deep conversation about the divide between the classes in their world. Another plot idea might be that Kaname is paired with a human who is afraid of vampires at first, but during those 7 minutes, he shows her a different side of vampires that makes her question her prejudices. Or perhaps a group of characters play the game and it leads to some revelations about their hidden feelings for each other, like Zero having to confront his feelings for Yuki when they are paired together.
To develop their characters further, you could explore their family backgrounds more deeply. Maybe Haruka has a family secret that Juri helps him uncover, which in turn changes his view of the world. For Juri, you could show her vulnerable side more, like when she's faced with a situation she can't control with her usual strength.
For Naruto, his brash and determined personality could be tempered by the secrecy and discipline required in the Anbu. He might learn to be more calculating and less impulsive. As for Kakashi, his laid - back exterior could be peeled back to show his more intense and protective side towards Naruto in the dangerous Anbu world.
For Peter, his sense of humor can shine through in the group chat. He can make jokes about his superhero life, like how he always has to run off in the middle of things because of Spider - Man duties. This shows his ability to not take himself too seriously despite the heavy responsibilities.
You could also develop their characters through their interactions with other characters. Zero's relationships with other vampire hunters or his classmates could influence how he behaves with Kaname. And Kaname's interactions with other Purebloods could affect how he approaches Zero. For example, if Kaname has to deal with a Pureblood who is jealous of his relationship with Zero, it could bring out new aspects of his character.
In a high school setting, Jellal's personality can develop as he tries to fit in. He might be initially reserved and not very talkative, but as he gets involved in school clubs or teams, he starts to show his leadership skills and his loyalty to his friends. Erza's personality can be developed by having her face challenges outside of her comfort zone. For example, if she has to participate in a group project where she's not in control, she can learn to be more collaborative and less overbearing. Also, her relationship with Jellal can bring out a softer, more vulnerable side of her that we don't usually see in the original Fairy Tail.
Sasuke could be developed as a brooding and mysterious vampire. He might be struggling with his vampire nature, like the urge to feed on his classmates. Sakura could be the one who helps him come to terms with it. For example, she could show him that there are ways to control his thirst without harming others.
In a high school setting, Naruto's impulsive nature might lead him to get into small troubles at school, like getting detention for being too noisy in class. However, this also shows his liveliness. Fem Sasuke, on the other hand, can be portrayed as the quiet and mysterious girl. Her intelligence can be highlighted when she participates in academic competitions. As Naruto tries to get closer to her, he discovers that beneath her cold exterior, she has a strong sense of justice, which is similar to his own. This realization makes him respect her more and deepens their relationship.
They could start by sharing secrets. For example, Takuma could tell Yuki about his past experiences that he hasn't shared with anyone else. This would create a deeper bond between them. Then, they could have some common goals, like protecting the school from a new threat. Working towards this goal would make them rely on each other more and strengthen their relationship.
