As he watches the famed Toake Daigo pull off another rescue so daring others might think it impossible, Fire Sergeant Onoda Shun thinks back to their days in special rescue training together, and how their working relationship began.

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...

Daigo, Shun, and Yuki struggle to complete their task in the fire fighting training tower. Yamagami's evaluation of their group is not at all what they expect, but they learn about an additional rule of the Special Rescue Corps.

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.

After his heroic efforts in Ariwara district, Daigo is hospitalized. In fact, he had dislocated his shoulders many times in his past and was scolded for it by the nurses. While talking, Daigo remembers the time he became “Toake Daigo.”

With a typhoon approaching, Shun and his squad have to move out. For some reason, Daigo ends up being locked in the basement! Will they be able to rescue the survivors as the rain water keeps flowing into the basement?

The typhoon has caused severe flooding. Shun and Igarashi dive into the water with their respirators to help Daigo and the survivors from a basement that is steadily filling with rain water.

The door that had trapped Daigo and the two survivors is finally open. Where will the water that rushes out in an instant take them?! Meanwhile, Shun was diving underwater with his face mask on for the rescue operation...

The Fuwa Rescue Squad leaves the collapsed road. Feeling the weight of the lives they couldn’t save, Daigo and Shun fall into silence. Watching them, Yamagami reminisces about how far they’ve come.
