Black and White Usually

In an inexplicable world setting, a 16-meter-old girl is chasing a group of special forces with a samurai sword that is the same height as her? The daughter of an official wants to overthrow her father with her gangster boyfriend? Do you want to take both black and white? In this difficult and dark world, I once walked alone for a long time. Even though I had many partners later, I still felt insecure until I met you, who allowed me to just be a happy woman. This novel and its characters are purely fictitious.
