Are you ready to be scolded for no reason? Are you sure you're ready for that?
The song will heal your heart.
In this world, one in ten thousand people is born with special abilities. However, most of these abilities are incomplete, and a perfect ability user has yet to be discovered. On a bitterly cold winter day—the kind news reports describe as severe—the Raikan Research Institute, led by Mikoto, took Guest, an ability user, into custody. So far, so normal, but it turned out that Guest was a rare specimen: a complete and perfect ability user! While Guest is under the jurisdiction of the Raikan Institute, research facilities from all over are now clamoring to get their hands on Guest due to that perfect ability.
...Also, it seems everyone just can't help but want to dote on Guest.
