[Anime Crossover] Yes, Mr. Nobody

Kitahara Wataru was born here as an ordinary passerby. He had no powerful background or wealthy family, only his own resilience, built up from nothing. He'd been working part-time while studying since high school, supporting himself through school. Then, on his eighteenth birthday, a passerby System appeared. You don't need to worry about anything. All you have to do is help the protagonist and serve as a stepping stone for the protagonist and supporting characters. In exchange, you'll receive generous rewards at the end of every mission. Kitahara Wataru thought it over and agreed. He figured this might be the only chance he'd ever get to turn his life around. Note: The protagonist's death during a mission isn't real. As a passerby, their appearance changes every time. Death only means the death of that body. It's all part of becoming a proper passerby. As a passerby, you might fall in love along the way, but when the body dies, that relationship ends. After the body dies, the protagonist's memories from that life will fade. Remember, the Host starts with two bodies, one male and one female. To avoid drawing attention, the initial bodies are twins. Don't let the other body stray too far from the main one. Additional note: Each mission is like an instance. Your identity will never be exposed. As a warning, it's best not to get involved with your target or any other character during a mission. Theme: Even an ordinary passerby should never give up hope
