Jyuki Ningen Jumbor

In a rebuilt future where construction teams use heavy machines to survive and reshape a world battered by nature, Jumbor leads a renowned crew from a small country. During a tunnel reconstruction project, a stronger rival team seizes the site. Jumbor is killed while trying to protect his teammates from their attack. Five years later, he awakens in a partly mechanized clone body with a physical age of five. His robot arms respond directly to his brain’s signals, and he discovers that his new body is powerful. He learns that his country is gone and that the king and princess have disappeared; he is also told that he is the last of his series.
