如月 みたま

A school teacher with nursing license at the protagonist's school... in other words, a the school's nurse.
She's a rare female teacher at the all-boys school who's very popular thanks to her calm and gentle personality.
At least that's how she appears on the surface making everyone adore her, but in private she's completely good-for-nothing.
Although she's a no-good big sister, she's first class when it comes to making the protagonist spoil her.
Today too, she spends her time lazily, completely depending on Naa-kun (that's how she calls the protagonist).
