Kyomi's is very straight foward and to the point. She never wants to mess up schedules and is said to be "niji's best friend". I imagine her voice to be quite monotone but also have that tsundere attitude to it and has confidence.

The first line is a very basic,short,snappy phrase.

The second line is subtle and happy at the start and turns quiet at the end like she's mumbling.

The third line is her raising her voice in fustration. It needs to have a build up like sharp,short breathing at the start.
