Heartwarming / ONIMAI: I'm Now Your Sister!

• Basically any time Mahiro relaxes and lets himself enjoy being a girl.
• Also any time we see Mahiro and Mihari bonding as kids. It really does show how close the two of them were, before they started to drift apart.
• Mihari helping her brother through his first period. Giving him something warm to ease his cramps and offering advice.
• When Mahiro fails to reach the toilet in time, Kaede gets him a spare pair of underwear, and promises to keep it secret. From that point on, Mahiro starts to see her as a second sister.
  • In the same episode, Mahiro looking after the house while his sister is sick, despite having no housekeeping skills. He doesn't do the best job, but the thought alone is enough to make Mihari happy.
    Mihari: In a way.. it's just like old times. Our roles are a little reversed, but... I'd love it if we could stay like this just a little longer.
• Mahiro and Momiji's first meeting. Despite not knowing Mahiro, she still insists on helping him with his shopping, just because it's a nice thing to do.
