Pc-Sama is the most mature, knowing she is the most developed and most used and stays out of fights, she knows shes better but doesn't feel the need to prove it.

This is a comedic role so a high comedy exaggerated voice, she wants an older voice between early 20's to late 30's, she wants to be calm but knows shes better than everyone, the leader and in command but check the comic and choose you own voice for her it's mostly up to interpretation.
