>>45417999When vtubing was still young, a lot of people thought Sora faked her singing with programs because her ability was completely unbelievable in the market at the time and the premise was that she was an untrained high school girl. After she proved that it was actually her singing, she gained a reputation as a robot or as a human vocaloid because it was still completely unbelievable that a human could pull off what she does.
Her breath and pitch is still inhuman even compared to other top tier singers in hololive, they just have different strengths from her but basically no one can ever do her songs in karaoke.
