Well, 'out of sight visual novel' could potentially be about a story where the main focus is on things that are not easily perceived or are hidden. For example, it could be set in a world where there are secret realms or things that only a few characters can see. It might also deal with the concept of perception and how different characters view the world around them when there are elements 'out of sight'. Maybe it has a plot that revolves around a character trying to uncover the truth about something that has been concealed from them.
I'm not entirely sure if there is a book titled 'Out of My Mind' that is specifically historical fiction or nonfiction. It could potentially be either, depending on its content. If it's a story set in a historical context and the plot and characters are fictional but the backdrop is historical, it would be historical fiction. If it's a true account of someone's experiences or a historical event, it would be nonfiction.
