In this final volume, a violent fugitive on the lam hides in the school and decides to take Toyama's class hostage. Toyama would naturally risk it all to save his 5th graders, but it might mean that he won't be there to protect them in the future when the next crisis hits - which is right around the corner. With the school about to shut down and a crime still unsolved, Toyama and Reiko put their heads together and raise the suspicion of someone far more dangerous than the fugitive - someone with supernatural abilities!
