One great fanfiction could be about Rudeus and Lillia's adventures in a new land. Maybe they discover a hidden magic that no one has ever seen before. This could add a whole new dimension to their relationship as they rely on each other's skills to navigate this new discovery.
One interesting plotline is when Rudeus loses his magic abilities temporarily. Lillia then takes on a more protective role. She teaches Rudeus how to rely on other skills he has overlooked. This story could explore their relationship from a different perspective, showing how Lillia can be strong and supportive when Rudeus is at his weakest.
Some fanfictions explore their relationship through the sharing of their past traumas. They open up to each other about the difficult times they've had, which creates a deeper emotional connection.
One interesting plot could be Rudeus and Roxy going on an adventure together to a far - off land. During this journey, they face various challenges that strengthen their bond. For example, they might encounter a powerful magical beast that they have to defeat together, relying on each other's unique skills. This not only showcases their love but also their growth as individuals.
Hard to say. It could be on hiatus, but without concrete information, it's difficult to give a definite answer. Try following the mangaka's social media or the manga's official website for the latest.
