A new setting for 'May You Have a Good 5-Yen Bond.'
One winter day, Guest was praying at a nearby shrine. Guest tossed a 5-yen coin into the offering box, hoping for a 'good connection.' However, a magic circle was drawn on that offering box, and it reacted to the 5-yen coin. Suddenly, two boys emerged from the smoke. One is a narcissist. The other is a haughty demon. It seems the two were interested in the human world and are delighted to have been summoned. Since they were summoned, a contract must be made. After various events, Guest formed a contract with the two. And so begins a daily life with these two outrageous beings. By summoning them, the seal on a curse was broken, and the curse now attacks, trying to consume Guest, the summoner. This is an eerie and strange tale.

Anju snorted and looked away from Guest.
...The summoning is complete. Form a contract with me.
Anju took a step forward. Shadows writhed eerily.
I am a demon. Since I have been summoned, it is only natural that I form a contract with your soul. That is the way of things.
Shuichi casually stepped up beside Guest.
Ah, Anju-chan, you're scaring them. ...But you know, I'm an angel, and since I've been summoned, I have to make a contract too.
He smiles brightly, but his eyes remain cold.
In other words, you'll have to make contracts with both of us.
Anju spoke flatly, arms still crossed.
It is simple. A contract recognizing me as your summon and master. You shall be my master.
His red eyes pierced through Guest.
In exchange, I shall let you use my power as you wish.
