Voice: Chikahiro Kobayashi

A former soldier in the 1st Division of the Japanese Imperial Army. Due to his heroic deeds and demon-like fighting style during the Russo-Japanese war, he was nicknamed "Immortal Sugimoto." What makes him immortal is his ability to show amazing courage and his fast rate of recovery. In order to fulfill the promise he made with his comrade who died during the conflict, Sugimoto heads to Hokkaido to participate in the Gold Rush. He learns of the stolen Ainu buried treasure, and gets involved in battles for the gold with the extremely powerful 7th Division and diabolical escaped felons.

Voice: Haruka Shiraishi

A girl from the Ainu tribe Sugimoto encounters who is from the northern land. Not only is she able to understand the language of the people outside of her village, she is also has knowledge needed to live in the mountains and hunt. She is called the "Ainu girl of the new age" because of her name that means "new years" and "future," and she has thoughts not bound by old traditions. She begins a journey to avenge her father who was killed by someone who stole the Ainu treasure, and decides to travel with Sugimoto, whom she has discerned as a skilled warrior. The Hokkaido Wolf Retar will come to her rescue, wherever she may be.

Voice: Kentarō Itō

A genius escaped felon also called "The Escape King." Because he has repeatedly escaped, the number of years added on to his sentence surpasses the amount of time from his original sentence. He has the ability to freely separate his joints, and has needles and nails hidden in various parts of his body in case he needs to escape. He's one of the 24 prisoners with the map printed on his body, but decided that teaming up with Sugimoto would be the best option in his situation.

Voice: Houchu Ohtsuka

The lieutenant of the 7^th Division of the Japanese Imperial Army. He is an intelligence officer extremely skilled at information collection and analysis. In order to avenge his fallen soldiers due to miscalculations from the higher-ups at the pincer attack of Port Arthur during the Russo-Japanese War, he schemes to take of the 7^th Division entirely. He is filled with madness and greed, wishing to use the Ainu gold to allow him to obtain dominance over his own unit. The metal protector on his forehead is there to protect the large wound he got when he lost at the Battle of Mukden.

Voice: Jōji Nakata

The former "demon vice-captain" of The Shinsen-gumi who was said to have died at the Battle of Hakodate, but in fact continued to live on for 30 years locked away as a political prisoner. He has connections to the man who stole the Ainu treasure, and is the one who planned the escape of the prisoners with the map tattoos on their bodies. Almost as if he is continuing the fight for The Shinsen-gumi, he prepares to start a war to declare independence for Ezo. He's over 70 years old, but he is overflowing with youthful energy, and shows no faltering in his sword skills.

Voice: Kenjirō Tsuda

A lance corporal in the Imperial Japanese Army's 7^th Division. His father was also part of the same division, and Hyakunosuke himself is extremely skilled as a soldier. He excels at precise shots with his gun, and is even able to blow a bullet through an opponent's head without fail as long as they're 300 meters or less apart. He's good at using the standard-issue Type 30 rifles issued by the army in terms of range and accuracy, and although the weapon has little piercing power, his skills allow him to take down far-away enemies in one shot with it. He is called "Bat Bastard" for his tendency to change his attitude depending on the situation, and ends up facing off against Sugimoto during his travels alone.

Voice: Yoshimasa Hosoya

A private first-class in the Imperial Japanese Army's 7^th Division. He was born in the North-Eastern hunting village of Matagi, so he has the skills to survive in the mountains. Because of the Matagi's rules that forbid villagers to sneeze or even clear their throat in the mountains in order to avoid making noise, he is naturally a very quiet person and doesn't speak much at all. He throws away his homeland of Akita and joins the colonizers, remaining in the army even after the Russo-Japanese War ended. While chasing after Sugimoto -- who badly injured Ogata -- he encounters the Hokkaido world Retar who senses that Asirpa is in danger, which makes his Matagi blood boil.

Voice: Kenji Nomura

A martial artist known as "Undefeated Ushiyama" due to the fact that he hasn't lost a match in ten years. He has a muscular body built up thanks to extreme training techniques, and his bulky frame is so hard that he can bounce nails off of it. However, he has an unbearable amount of sexual desire, which sometimes is his worst enemy. He was locked away in prison because he slept with his master's wife. He is one of the prisoners with the map tattooed on him, and teams up with Hijikata due to their interests being similar.
