Power dynamics is a common theme. Given that Guy is extremely powerful and Rimuru is rapidly growing in power, how they interact in terms of who has more influence is often explored.
Their relationship could start as a cautious alliance. Rimuru, being a slime who has built his own community, would be wary of Luminous at first. But as they face challenges together, they start to respect and trust each other more.
In the 3x11 fanfic of Chloe and Lucifer, their relationship might be explored in unique ways. Maybe it shows a deeper emotional connection that wasn't fully shown in the original series at that point. It could also introduce new plotlines centered around their characters, like how they deal with a particular crisis together.
Among the main characters besides Rimuru are Gobta. He is a goblin who is rather comical at times but also shows growth throughout the story. Then there is Diablo, a very powerful demon who becomes Rimuru's subordinate. His power and knowledge contribute to Rimuru's rise in the world of the novel. There are also other characters like Milim, a dragonoid with a child - like personality who has her own impact on the overall plot.
Marinette can react by standing up for herself. She might confront Chloe directly and tell her that her actions are wrong. This shows Marinette's strong character.
On the other hand, Beca might become very withdrawn. She might isolate herself from others and just focus on her music as a way to cope with the heartbreak. This could be her way of trying to forget about Chloe and the relationship that just ended.
Dan would probably be shocked at first. He has a complex relationship with both Lucifer and Chloe. But he would also be concerned for Chloe's well - being and the future of the baby. He might offer his help in more practical ways, like making sure Chloe is safe during her detective work. Ella would be super excited. She's always positive and would probably start knitting baby clothes right away and be full of ideas for baby names.
I've heard of 'Guy and Rimuru: A Different Path'. In this fanfic, it takes an alternate universe approach. Guy Crimson and Rimuru meet under very different circumstances than in the original story. Their relationship starts off rocky but then they discover they have more in common than they thought, leading to a heartwarming friendship.
One interesting fanfic could be about their first encounter from a different perspective. Maybe it focuses on Guy Crimson's initial thoughts about Rimuru which were a mix of curiosity and wariness. In this fanfic, their relationship could develop as they face a common enemy together, gradually growing to respect and trust each other.
One popular Rimuru x Guy fanfiction is 'The Unlikely Bond'. It explores their unique relationship in a new world setting, with Rimuru's naivete and Guy's powerful presence creating interesting dynamics.
