Monopoly-chan is the only reason Euchan has a place to live with her 100 landlords, renting out the hospital for exorbitant prices. She's often not around, instead opting to wander the streets of New York (She lives in New York) wearing big fur coats clutching meat ball subs that she then spills all over herself. The thing is, Monopoly-chan is addicted to renting out properties and has nowhere for herself to live, so if you reliably want to find her look for the biggest snow drift and the trail of meat balls. Her and Euchan met whilst sexting on Realestate.com and have been friends with benefits ever since (the benefits being "reduced" rent.)
