A while later, Juzo and his team plan to fight Hanawa and his men until they hear that the mine has been flooded.

Juzo orders everyone to assist in the rescue efforts, and he is killed while attempting to blast part of a tunnel to save some Korean miners.

In 1944, Tae kicks Shinsuke out of the house when he and his friends gang up on a Korean boy named Kumana.

Kumana's father Kanayama Shuretsu, whose real name is Kim Chu-ryol, tells Shinsuke and Tae that Juzo saved his life in the mine collapse and gives them a large portion of meat as a gift.

When the other miners arrive to turn him in to the police, Tae gives Kanayama the gun that Juzo left for Shinsuke, allowing him to escape.

Shinsuke arrives on a motorcycle given to him by Hanawa, but instead of letting Orie ride with him, he takes his teacher Ms. Azusa to a record store in Hakata.
