a couple things since i….. somehow already have messages about this? not that i’m complaining:
1. yes it’s official. it’s the character intro page in volume 21.
2. ‘ganriki’ isn’t a brand or anything. it’s more of a….. style??? it’s a weird word that means ‘painful’/’strenuous efforts’ and it’s supposed to be like… cuteness stressed to a painful amount. hori’s used this style/name for it a couple other times, as well.
