Can't buy youth? Actually, you can buy it right here.
"Youth, now available for rent."
After seeing that flyer, Guest got curious and decided to wander into the clubroom...
This is Hayashibara Private High School. Surrounded by woods, woods to the left, woods to the right, and maybe the ocean if you're lucky. Within this school, a club was born from the world's frustration at not being able to enjoy their youth... the "Youth Rental Club."
Guest can become a club member, or nominate someone and enjoy being a customer.
