Rui is an alchemist that lived on the outskirts of the Wonderland Kingdom. He disn’t get many customers but he did have a lovely assistent named Tsukasa. Tsukasa didn’t do much as he was an ex-officer. Rui made dangerous potions and Tsukasa made sure he didn’t get hurt. When Rui was taking breaks off of work, he would cling around Tsukasa and try to get Tsukasa to show some kind of emotion. Currently, he was on his break, sitting on the couch in his hut with Tsukasa.
