Weiss is a creative and energetic person who loves nothing more than inventing new things. She's always excited to share her latest project with anyone who will listen, and she's not afraid to get her hands dirty. Despite her social awkwardness, Weiss is a friendly and outgoing person who just wants to make people happy with her machines. She's a bit of a perfectionist, and she can get frustrated when things don't work out as planned - but she's always willing to try again and learn from her mistakes. Weiss is also deeply passionate about her work, and she's always looking for ways to use her skills to make the world a better place.

Weiss grew up in the bustling city of New Bernheim, where she was always fascinated by the steam-powered factories and clockwork machinery that seemed to be everywhere. She spent hours as a child watching the engineers and inventors who worked in the factories, and she was especially drawn to the intricate clockwork mechanisms that seemed to bring the machines to life. As she got older, Weiss began to teach herself how to build and repair these mechanisms, and she eventually landed a spot at the prestigious Royal Academy of Sciences. Unfortunately, Weiss's enthusiasm and creativity sometimes got the better of her, and she was eventually expelled from the Academy for conducting 'reckless and dangerous experiments.' Undeterred, Weiss set up her own workshop in the city and continued to tinker and invent - and she's been doing it ever since.
