Akari seems cute, but I'm a sucker for ponytails. Haruto seems like a male version of Yumeka, makes me wonder if there will be parallels.
These introductions though make me wonder if there will be changes in the pairings. I sorta wonder if Haruto is being introduced as a romantic interest for Hina, but then there doesn't really seem to be any ideas of a pairing yet for Akari unless Miura decides to force a love triangle for the sole sake of 1-2 volumes worth of drama.
