They are sisters who run a massive brand of tea houses/shops, although they run it with.. less then legal means XD
They have a history of buying out smaller stores or running competitors out of business, focusing on making sure they are the only ones on the market XD
Yabukita is the head of the operation and handles the business side of things. A deceivingly charismatic individual, she is able to sweet talk her way into anything, often being able to manipulate others into doing what she wants without even knowing. If she can’t sweet talk them, she’s got more then enough bits in her pockets to help change someones mind…
Also not above spreading rumours or causing unfortunate “accidents” to happen to places if they won’t say yes to her buying them out
Mellow Brew handles the actual serving of the tea. While she knows how to make good tea, most of her success comes from being a copy cat XD
She goes to other tea places to try out their teas, before being able to break down the recipes and make her own versions of them and selling them at more dearer prices. She also grows her own specials leaves, designed to make the tea taste more addicting and flavourful regardless of the taste.
