I'm not sure specifically what 'jitaku keibiin 2 visual novel' is about as I haven't experienced it directly.

I'm not entirely sure as it could be a rather specific or niche visual novel.

You could try looking for it on popular visual novel platforms. Some well - known ones include Steam, which has a wide range of visual novels available. Another option might be to check out some dedicated visual novel websites where independent developers often publish their works.
Good plot, interesting characters and vivid art style are essential. A complete manga usually has a clear beginning, middle and end, and can draw readers in with its unique story and visuals.
