The "destined three" are assigned to a firefighting exercise together, where they must rescue a dummy from a training building that's really on fire. When they realize a true survivor would never survive the smoke, a difficult decision awaits them...

Half a year after their training, Shun is finally going to work with Daigo in the Fuwa Fire Station’s Special Rescue Squad. He’s nervous about his first day when suddenly they have to move out! On the scene, Daigo does something surprising!

“Please let me go.” With those words, Daigo actually dislocates his own shoulder and goes into the crevice in the rubble. What an unbelievably calm way to continue the rescue mission.
