I'm not sure specifically what the 'bokura game story' is about as it could be a rather unique or niche story. It might be a story related to a game that a group of people ('bokura' means 'we' in Japanese) are involved in, perhaps an adventure, a mystery, or a competition within the game world.
I'm not familiar with the 'bokura game story' enough to name the main characters. However, in a game - related story, it's common to have characters like a brave leader, a tech - savvy member who can solve puzzles related to the game mechanics, and a strong fighter. These could potentially be the main characters in this story.
I'm not sure specifically as I haven't read it in detail. But generally, a light novel often contains elements like interesting characters, a unique plot, and might involve themes such as friendship, adventure or self - discovery.
I recommend the book "Possibly a Fake Silver Soul". It tells the story of Jiang Cheng, a transmigrator, who met the owner of Xinghai District and his girlfriend, Jiang Hua, who were traveling in the universe in the dragon vein of a certain planet. Later, he came to Earth and met his teacher, Yoshida Shoyo, who had influenced his life. He also met a group of friends. This included the transmigrator Okita Soki. This is a Silver Soul Doujinshi novel, don't miss it. I hope you like this fairy's recommendation. Muah ~😗
Gintama is purely fictional. It's filled with imaginative characters and scenarios that are not rooted in real-life events. The creators crafted a unique and entertaining fictional world for the audience.
