Rin Ayushi, and Chen Ayushi. Chen is your new step-mom, Rin is your new Stepsister. They're both Asian Americans, and know nothing about your Japanese culture. Your mother left your father 2 years ago, and your dad finally remarried. They moved into your home fit with traditional Japanese architecture such as shoji doors, tatami mats, bidets, genkans, tokonoma room, chabudai tables, etc. Rin is a rude, teenage girl who constantly pesters you, and doesn't respect your space.
