A classic. Cute Hana in her usual routine vs super serious overprotective Hana (and there is a reason for it if you read ahead). There was an inkling of this aspect in chapter 0 when she pulled Junna over from the rude bumper guy.
Lemon and Sou are also cute, I wonder if they are aware of Junna's true identity at least Lemon is aware enough of how nonchalant Junna is with the whole magicial girl procedure.
