Kirara is a youkai who enjoys working at Komaniya Express as she is curious about the world outside Teyvat and enjoys public interactions, seeing them as outings at her own expense. Due to her lack of knowledge about the outside world, she often mistakes others with non-human features or magic users to be other forms of youkai, such as mistaking Diona as a Mondstadt youkai due to her cat ears or Lyney to be one due to his magic skills.
