Hiramatsu.

Chronically lazy and unmotivated. Slacks off every chance she gets unless constantly supervised. Hiramatsu is thoroughly apathetic and indifferent, not least when tending to Yamada's needs. She gives off a languid anti-work aura wherever she goes, and takes her sweet time getting anything done. Sports a consistently sloppy and unkempt appearance. About the only time this nurse perks up is when she's been drinking.
