Some of the existing Naruto series characters might also play important roles. Kakashi, for instance, could come to the Rain Village to assist Naruto or to investigate something. His wisdom and combat skills would be valuable in the story.
Naruto is likely to be one of the main characters, of course. He would be the center of the action in the Rain Village setting.
Of course, Naruto himself is very popular in these fanfictions. Writers often put him in situations within the Rain Village that test his beliefs and his ninja skills. For example, he might have to face off against a new and powerful enemy in the Rain Village while also trying to understand the complex politics of the village.
There's also the type of character who is an outcast in the Rain Village but has a heart of gold. They might be shunned because of their different beliefs or appearance. In fanfiction, they often end up becoming the hero, proving everyone wrong and uniting the village. This character is relatable and interesting to readers.
Rain is the key character here. He's the one in the difficult situation of being shackled to the Dark Gundam. The Dark Gundam is not just a machine but can be considered a character with its own motives and powers. Additionally, there could be a mentor - like figure for Rain. Maybe an older, more experienced pilot who has some knowledge about the Dark Gundam and tries to guide Rain in his struggle. There could also be antagonists other than the Dark Gundam, such as those who oppose Rain's attempts to free himself for their own self - serving reasons.
Well, it could be a young man and a young woman. Maybe she is a shy artist who loves painting in the rain, and he is a kind - hearted passer - by who is attracted by her unique charm in the rain.

Not having read the 'big rain story', it's just speculation. But it could feature characters like a young child who is frightened by the big rain and the thunder that comes with it.

Well, without having read the specific 'Romance in the Rain' novel in detail, generally in this kind of story, there would be the two lovers at the heart of the romance.

They play a role in shaping the relationship of the main characters.

But as time passes, their relationship changes, and Charlie becomes more empathetic towards Raymond, and they both grow in different ways through their interactions.
