Taiyo and the others learn that the Spy Association HQ has been rigged with bombs. They have less than an hour before they explode! They must stop them, or the ensuing drastic accident will involve legitimate society as well. The intruders have the ability to shape-shift into staff members or spies, and led by Kai, the Gold Rank spies split up to search inside the HQ. Taiyo, along with Ryu and Shinzo, visit the Training Wing, where the children living at the HQ are hard at work. The kids come running when they see Ryu, and soon they're having a lively conversation, but... ?!
