There are often mages or wizards. They might be the ones who accidentally or intentionally caused the reincarnation. Another typical character could be a healer who tries to understand the nature of the skeleton's existence. There might also be adventurers who cross paths with the skeleton, either becoming friends or foes.
There probably are. Maybe there's a mage who helps the skeleton understand the magic system in the world. Or a warrior who at first is skeptical of the skeleton but later becomes an ally.
In the '3 Skeleton Key' story, the principal characters are the three lighthouse keepers. These men are in charge of maintaining the lighthouse at 3 Skeleton Key. They have to face the unexpected and terrifying situation when a shipwreck brings a mass of rats to their lighthouse. Their individual personalities and their collective will to survive are what drives the story forward as they battle against the overwhelming number of rats that threaten their lives and their lighthouse.
Since the novel focuses on the skeleton key and a mysterious house, the main character is probably a woman who is hired to work at the house. She is brave enough to explore the secrets. There may also be an old family member or former servant associated with the house who has some important information. Their interactions and the main character's determination to unlock the secrets with the key form the core of the story.
There could be a character named Kuro, who has the skeleton bloodline and uses it to create bone wings to fly. Another is Yuki, who can freeze her bones and use them as ice - like weapons.

The skeleton soldier is obviously one of the main characters. There is also likely a mage or some sort of guide figure that helps the skeleton soldier on its journey in the story.
Since I don't have detailed information about this specific visual novel, it's hard to say for sure. But obviously, the skeleton girl is likely to be one of the main characters. There might also be other characters like friends or foes she encounters in the story, perhaps a wizard or a brave knight if it has a fantasy setting.
