I'm not sure who the main characters are as I haven't read the Pandora Star novel. But they could be scientists, explorers, or people with special abilities who are drawn to the Pandora Star for some reason.
The main characters in the Pandora story are Pandora herself, Zeus who was the king of the gods and masterminded the whole thing, Hephaestus who created Pandora, and Epimetheus to whom Pandora was given.
I'm not sure who the main characters are without reading it. But likely Pandora herself would be a main character as it's based on her box.
Oz Vessalius is one of the main characters. He is a young nobleman with a mysterious past. Then there's Alice, a powerful being. And Gilbert, who is loyal to Oz.
If we assume it's based on the Greek myth, Pandora could be the main female character. For a male character, it could be Epimetheus, who was Pandora's husband. In a more modern adaptation of the 'pandora love story', the main characters could be entirely new creations. For example, a Pandora - like character who is an artist and a man who is a journalist, and their different worlds collide to form a love story.
I don't have specific information on this visual novel, so I can't say for sure who the main characters are.
Since I haven't read the Pandora Hearts Cacus Race Novel, I can't say for sure. However, in the Pandora Hearts series, there are characters like Alice who is quite significant. In this novel about the Cacus Race, there could be characters directly related to that race who play the main roles, perhaps a Cacus Race leader or a young Cacus who has some special destiny within the story.
In some cases, it's a male avatar. He is created to interact with the Pandora environment and its inhabitants. He might have to deal with identity issues as he is part human and part something else. He gets involved in the conflicts and relationships on Pandora, which makes for an interesting story. For example, he could be caught between the interests of the human colonizers and the well - being of the Na'vi.
The main character is Harry. But in Pandora, he would meet a variety of characters. There could be a young Na'vi who becomes his guide, showing him around Pandora. Also, there might be a human scientist on Pandora who teams up with Harry. This scientist could be interested in the magical aspects Harry brings and together they could face the challenges in Pandora, both from the natural elements and the power - hungry humans.
The Pandora Star novel's plot could be multi - faceted. It may tell the story of a discovery related to the Pandora Star. This discovery could lead to political intrigue among different factions in the story. There could be a race to control the star or its resources. Characters might have to face personal and moral dilemmas as they interact with the Pandora Star and all that it represents.
In 'Pandora Revealed High School Story', Pandora is the central figure. There may be a group of friends around her. For example, there could be a boy named Jake who is good at sports and is always there to support Pandora physically. And then there might be a girl named Mia who is really smart and helps Pandora figure out the more intellectual parts of the mystery. There could also be an antagonist, like a bully named Max who tries to stop Pandora from revealing the secrets of the high school.
