There's a funny thing involved re: Nico drinking Red Akumas in #newmelodyproject . She, canonically, does not like spicy stuff. Her drinking a drink made partly of whiskey and jalapeno is all about how, when we catch up to her at the start of the series, she's got this kind of vaguely "more mature" image as an idol (she has been doing it for a decade at that point). It's why she's wearing her hair down and, begrudgingly, not doing "Nico-Nico-Nii" at first.
In her brain, she latched on to this drink - whiskey, jalapeno, blood orange juice, agave - as part of being "mature." Over time, the sweet part kind of smuggled the spicy in and she actually develops a fondness for the drink in spite of the spiciness.
(Also, subconsciously, a drink with "red" in the name probably reminds her a bit of the girl that isn't in her life anymore at the start of the series...)
Literally none of this really comes up but it's a part of her characterization. I just got super hyper nerdy about it in a way that most people will never care about 😅 #lovelivenewmelodyproject
