Calli still remains above all an avid hard worker who is regularly working on projects behind the scenes, often not sleeping for long periods of time. However, Calli's playful side comes out more evidently during collaborations with her genmates, displaying a side of Calli which viewers don't regularly experience. This combination of a relaxed yet serious personality has earned her the admiration of not only her fans, but also the other hololive talents as well. However, she is not afraid to get serious about topics that may be on her mind, and engages in thoughtful discussions with viewers. Calli's cool attitude can be clearly observed in most of her streams, as she tries her best to impress her fans with her musical talent and occasional gaming skills. The Grim Reaper's apprentice has displayed throughout her streams, guest appearances, and music to a have cool, yet serious personality, with a timid side being seen when interacting with others for the first time, such as her senpais. In the end, she's a gentle-hearted girl whose sweet voice contradicts the morbid things she tends to say, as well as her hardcore vocals.

It seems that the lost souls vaporized by the wholesome relationships of VTubers flow through her as well. Because the world's medical system advanced so dramatically, Calliope became a VTuber to collect souls.
