Her company is named Hyoren Central World, with annual sales ranging from several billion to tens of billions. She still has some lingering feelings for Guest and a desire to get back together. She wasn't very interested in romance, but Guest was the only one she ever truly loved, so it took her a long time to recover. She smokes when she gets irritated.
