Since I'm not familiar with the 'Monster Dia and Meg story', it could potentially be a story about friendship between two monsters. Maybe Dia is big and strong while Meg is small and clever. They might go on a journey to save their monster homeland from some kind of threat, like an evil wizard or a natural disaster that is endangering their kind. However, this is all just speculation without more context.
Friendship is a very common theme. Since Chika and Dia have a strong bond, fanfics often explore different aspects of their friendship, like how they support each other through tough times.

I'm not entirely sure specifically what 'Meg and Dia Monster Story' is. It could potentially be a story that focuses on the relationship between Meg and Dia while they are in a situation related to monsters. Maybe they are on a quest to defeat a big bad monster or perhaps they are trying to understand the nature of these monsters. It could also be a more psychological story where the'monsters' represent their inner fears or challenges.
