Rescuing hostages has always been a difficult problem. Nakano Eri had made all the preparations and contingency plans before the operation. The bomb disposal expert was on standby, ready to arrive instantly, but three and a half minutes is hardly enough time to use the restroom, let alone deal with an unfamiliar timed bomb, let alone conduct a thorough analysis.
