Obviously, the werewolf king's wife is one of the main characters. And the werewolf king himself is likely to be a major character as well, since the story is related to her being his wife.
There could be other important characters too. Maybe there are some trusted advisors or friends of the werewolf king's wife. They could play important roles in her story, like helping her out in tough situations or giving her valuable advice.
It's possible that there are some antagonists in the story. They could be rival werewolves or some external forces that threaten the werewolf king's wife or the kingdom. Their actions and interactions with the main characters would be part of what makes the story interesting.
It might be about the special adventures or events in the life of the werewolf king's wife that are not part of the main story. For example, it could be about her early life before meeting the werewolf king, or some secret relationships she has within the werewolf community.
Since it's called 'Loving the Cursed Werewolf King', the two most obvious main characters are the werewolf king who is cursed and the character who loves him. There might also be other important characters like members of the werewolf king's pack who could either support or oppose their relationship, or perhaps a witch or wizard who has something to do with the curse.
The main characters could be the werewolf children, of course. But also, there may be a group of humans who discover the existence of these children and either try to help them or hunt them down. Additionally, there could be a female werewolf figure who acts as a mother - like figure to the children, teaching them the ways of the werewolf and protecting them from harm.
In 'the first werewolf story', the werewolf is obviously a main character. It is the source of all the action and mystery. Then, there might be a brave hunter who decides to track down the werewolf. This hunter could be motivated by protecting the village or seeking glory. Additionally, if there is a backstory about how the werewolf came to be, there could be a character like a witch or a sorcerer who cast the spell that turned the person into a werewolf.
The main character is likely the bride. She is probably a human or some other non - werewolf entity at the start. Her journey into becoming the werewolf king's bride would be central to the story. This could involve her being thrust into the werewolf world, dealing with the politics and power dynamics within the werewolf community, and falling in love with the werewolf king. Maybe she has special powers or qualities that make her a suitable bride for the king, or perhaps she has to overcome her own fears and prejudices about werewolves.
I'm not sure as the name doesn't give away the characters directly. But it could be lovers who are trying to figure out their relationship using the love equations.
The protagonist is one of the main characters. And there are various Servants like Saber, Archer etc. Each Servant has their own distinct personality and abilities that play important roles in the story.
Not having read it, I can only guess. There might be a protagonist among the regular passengers who has to deal with the extra passenger. There could also be a character who is initially hostile to the extra passenger, and another who is more sympathetic. Maybe there is an authority figure like a conductor or a ship captain if it's a story set in a vehicle or on a ship.
Since it's an extra story related to Soma, it's likely to feature the main protagonists from the original game. They might be joined by new characters as well. These new characters could be related to the existing ones in some way, like being from the same organization or having a common goal. However, without more information, it's hard to say exactly who the main characters are. It could also be that some minor characters from the main game get more spotlight in the extra story and become main characters in this new narrative.
We can assume that the central character is the so - called 'extra' in the academy. However, there could be other important characters too. There might be a group of friends that the extra makes along the way. These friends could be other misfits or students who see the value in the extra. There could also be a love interest, perhaps someone who sees the extra for who they really are and not just as an unimportant figure in the academy. And then there are likely to be some authority figures, like the dean or headmaster, whose actions and decisions impact the extra's journey of survival.
