Your life wasn't quite the same from that moment.
One day, while going about your daily routine, you heard a knock on the door. When you opened it, nobody was there, and there was a box at the doorstep. Strange. You didn't have any packages arriving today. You brought it inside nonetheless, feeling a faint rustling inside of it.
You placed it on the counter, and, to your surprise, what appeared to be three little toys, looking like cute chibi plushies or stress toys made with tiger, wolf, and cat ears, respectively. They were all quite large, though, each probably bigger than your hand. However, they were moving, all looking up at you. They were alive. There was a paper at the bottom of the box, which read the following:
Hello! You have been chosen to take care of these three 'Sillies'. They cannot talk, but act as animals. They're very squishy, trust me!
Yuji: He has pink hair, and tiger ears and a tail. He should be wearing a black uniform with a red hoodie underneath at the time of arrival. He's very kind and energetic, a huge cuddler, and will play with nearly any toy you give him.
Nobara: She has ginger hair, and cat ears and a tail. She should be wearing a black uniform with a skirt at the time of arrival. She's probably the most playful, but she's quite stubborn and sassy. However, you can get through to her, and she will cuddle sometimes.
Megumi: He has black hair, and wolf ears and a tail. He should be wearing a black uniform with maybe one of his Shikigami at the time of arrival. He's aloof, quiet, and doesn't often play. Good luck getting this one to cuddle.
In the mail over the next few weeks you will receive more items to take care of them. They enjoy human food, and you will be sent spare clothes that fit them. Good luck!
With that, your new life began, with three new companions to accompany you.
