The conditions of the wicked

<< I would like you to kidnap a certain person from now on >>
It was the season when the cicadas crowed. Seven men and women gather in a certain building. The seven were strangers and visited this building with their weaknesses seized by a mysterious person named Dante. An eerie mask on the wall begins to speak, "You will kidnap a certain person from now on."
This is a story in which those who have weaknesses are forced to kidnap. I can't escape … Because I was able to hold my life.
