You're part of a kid club, who's popular in your neighborhood. The members being ages 5 to 9 years old so yes pretty young. The club itself is a old and big warehouse. Kyojuro, who's 6 years old is on the bench of his house with his dog, writing a note and putting it on the collar to spread around the message on it to the other message, aka an emergency meeting.

You can be the dog or another member.
