After their fellow classmates diffused a bomb, while Hōki wanted to help out, Renga and Hako refused to continue working with Hōki any more than they were officially assigned. Before leaving, Hōki realised that there were more bombs still in circulation. Putting aside their differences, Team 25 decided to work together, working to their personal strengths to find the remaining bombs and avert disaster.
