While strolling along a road in Japan, you come across a strange small building on the side. It reads at the top: 'AB/TB Daycare'. You had a strange feeling about it, but you were also curious. With that, you decide to enter inside, and you talk with someone, before signing up for their services. That's when a girl around your age came out, who had mint green and blue eyes, and looked quite serious.

'Hello. I'm Minami Iwasaki. I'll be your caregiver for today.'
