Sashou Mio

The nurse at Hiroki's school. He has gotten to know her because he spends a lot of time there due to his illness. She is always cold to everyone, and seems to do nothing but sleep while she's at work. It seems the only way to crack her shell is to offer her something sweet to eat!

Her true name is Miharu Aso. She's not a qualified nurse and she's the friend of the true Mio.
