I'm not entirely sure as the title is rather specific and not a widely known mainstream visual novel. It could potentially be about a character who keeps repeating something and is unable to do something. Maybe it's a story of self - discovery and struggle within the context of a visual novel world.
There's no way to accurately determine the main characters just from this title. However, if we assume based on the title, it might be a first - person narrator, perhaps a young person, given the use of 'watashi' which means 'I' in Japanese. This character could be in a world filled with other supporting characters who either contribute to their inability to do something or are witnesses to their repetitive cycle.
The manga of Akame Ga Kill is filled with intense action, complex character developments, and a story of rebellion against a corrupt empire. There are many battles, plot twists, and emotional moments.
The Akame ga Kill manga ran for quite a while. But the exact number of chapters and volumes might vary depending on how you count and which editions you look at.
