>>2538645her genmates who know her, and lamy herself, have freely talked about how Lamy loves to drink a lot. they've told some stories about it too.
but I suspect it got too embarrassing for Lamy to be seen as a drunkard as her main characteristic, i know i'd be worried if that were me. you can see this in one of her recent Monster Hunter collabs with botan, botan joked about lamy being full of alcohol is why the monster didn't want to eat her, and Lamy was all like "hey don't say stuff like that! people are going to get the wrong idea about me!" so she's definitely trying to get people to stop seeing her as an alcoholic.
