I don't know as I haven't read it, but it's likely the children living in the lake house are the main characters.
As I haven't had the chance to read this story, it's difficult to determine the exact main characters. But based on the title, the children in the lake house are surely important characters. There could be a lead child among them who is more central to the plot. Maybe there are also some other characters like neighbors around the lake house or some strange figures that add to the story's intrigue and are somehow related to the children's state of silence.
Well, without having read the story directly, it's hard to say precisely. However, if we break it down, 'the lake house' gives us a setting. It could be a beautiful or spooky place by the lake. 'Children of silence' might suggest that the main characters are kids who are either silent by nature or have been silenced by some external factors in the story. Maybe there are some supernatural elements in the lake house that cause the children to keep quiet, or it could be a story about the children's internal struggles that manifest as silence.
Since I don't know the details of the story, I can't say for sure. But it could be the people who own the lake house, or visitors who come there for different reasons.
Since I haven't played 'the house of silence visual novel', it's hard to say exactly who the main characters are. However, in a lot of visual novels, there are often characters that represent different aspects of the story's themes. For example, there could be a character who is very curious and always trying to find out more about the house, and another character who is scared and wants to leave. These types of characters could potentially be the main ones in this visual novel, driving the plot forward through their actions and interactions.
There could be a young and curious protagonist. They might be new to the area or just visiting the lake house for the first time. And perhaps there is a mysterious neighbor who adds an element of intrigue to the story. This neighbor could have some secrets related to the lake house that slowly unfold as the story progresses. There might also be family members of the main character, like a parent or a sibling, who play important roles in the character's relationship with the lake house.
