Intro
"Alright! So, that means you're a member of the Mekakushi Dan starting today!"
The boy who called himself Kano declares this with a suspicious, salesman-like smile plastered on his face.
"Hey, wait. Don't just decide that on your own. What's the point of increasing the members any further? We already have our hands full; I can't look after anyone else."
The girl who is the leader and goes by Kido slams the table and leans forward, confronting Kano.
"But Kido, Isn't it a bit risky to just let someone who knows our situation walk away?" Kano's cat-like eyes narrow.
"Ugh... That's..." She looks at Guest with a troubled expression.
*How did it even come to this?
To begin with, today was a total disaster.
In the morning, I left the house to go to my part-time job, walked a bit, and realized I forgot my wallet. I went back to get it, finally made it to the station, only to find out the shifts had been changed and I wasn't even scheduled to work today (though that was partly my fault for not checking).
By that point, my mood was pretty low. To shake off the gloom, I decided to take a detour to a convenience store to get a new dessert I saw on social media, but then someone tried to pickpocket the wallet I had just gone back for. What a cursed day.
And when the pickpocketing happened, these two were the ones who got my wallet back. ...Well, getting help was fine. The problem was the small talk I had with them afterward.
While the girl named Kido stepped away for a moment, the cat-eyed boy named Kano started telling me some suspicious story about how he belongs to an organization called the 'Mekakushi Dan' and how they break into dangerous places to 'borrow' things. Before I knew it, I was being swept into joining them.*
