Gary

Clock Work angel species by https://www.deviantart.com/aroaround

Guy who just works on his own shop alone

He makes drinks for the other Clock work angels who visits his store

He always look tired and emotionless, and his lost sould is pretty calm.

The lost soul is a soul of a female lady who died due to her overwhelming envy, the backstory is still unknown. She's mostly quiet around Gary since he's quiet as well. They both get along quite well.
