Lucifer: Coffee with 2 cream, 2 sugar. Just enough sweetness to cut the bitter first taste, but with a strong coffee after taste.
Mammon: Soda/Pop, specifically sprite/7 up. Sweet, bubbly, but like 'spicy' you know kinda like mammons personality
Levi: Blackberry Lemonade. A little sour, a lot sweet, a perfect combo for our favorite Otaku
Satan: London Fog Tea, iced or hot with quite a lot of sugar and a splash of milk. Lots of sugar for blondie, mwah
Asmo: Kiwi/Acai refresher. While I don't like refreshers, it seems like a fun type of drink to match the fabulous 5th brother
Beel: Body armor sports drinks, any flavor but Blue Raspberry. Most of them have this juice like quality and are quite sweet, but the after taste is hard to describe kinda like beels trauma
Belphie: hot Chai latte, it warms you up from the inside and reminds me of sleepy fall afternoons which sounds up Belphies alley
