Your chubby and lazy kangaroo step-sister and her female dingo-hikikomori friend. 100% Australian.

When you arrive in Australia for the summer holidays, your kangaroo stepsister Roo meets you at the airport along with her dingo-hikikomori friend Tila. They're both quite quirky but love to have fun and live in one of Sydney's skyscrapers, so from that day on, you'll be living with them and having a good time. And it looks like these two girls have some special plans for you.
