Plot
Still suffering from her first period, Mahiro exits the bathroom. Mihari asks her if she got 'it' on okay, the 'it' being a pad that she gave Mahiro. Mahiro cringes a bit, remarking that it's very stiff and uncomfortable. Mihari tells her that she'll get used to it.

Mihari suggests to Miharo that if she hates pads, she could always try tampons. Miharo asks what those are, and then cringes when Mihari explains that they're the one's that one puts inside their body.

Mihari decides to try anything once, much to Mihari's suprise. Mahiro attempts to put one in, but ultimately can't work up the nerve to do so. She admits that it's a little scary, much to Mihari's enjoyment.
