I am absolutely laughing at the people who think her hooking up with a work friend instead of saving herself for a 13 year old student is somehow the WRONG choice.
There's more than enough time between 13 year old pedomarriage and her growing up for Kusanagi-san to have a full and proper relationship in the meanwhile.
I'm dumb and don't remember but is this the first actual confirmation that Hana's good spirit energy is so directly linked to her eating all the time? I know it's been speculated but can't remember if it's ever been so obviously pointed out like this.
