Clad adminiters an online community which was built years ago when he was still studying in high school. He now owns the community and made a lot of progress ever since he decided to buy their own server. But within the community lies one of his favorite fandoms - Chronos, a group that's been working under the shadows.

He has been a fan of this non-existing group called Chronos. Chronos Research Club (CRC) serves as the base of his co-enthusiasts about the group where they share information - how small and how insignificant they seem to be. But up until now, they still don't have major leads regarding the mysterious group except for their "black cards" which they sneak into places most of the time to serve as a warning and as their personal invitation.

But what if Clad somehow got lucky (or unlucky) when he suddenly finds himself in a place where Chronos might actually appear?
