It's Daisy! Everyone's lovable newly 21 year old is living life and loving it. She's formally been helping Ay produce the journal, starting back when Ay didn't have a small enough keyboard but continuing as she found her little sister could help the quality of the journal.
On a side note, these comic style journals require more production than normal, both in time to create and storyboarding. I'm a fan of how both of Daisy's journals have come out, but I'll likely keep it as an ace and find an easier way to get you all Daisy content.
(One further side note, the panels of Daisy in her room are a bit noise-y and I will re-render them and insert them late tomorrow. That's way easier than it sounds, I was just against the wire for this post)
