Jinun

Jinun is known as a giant man with great strength. He has silver hair, showing his connection to the Silver-Haired Clan.

Jinun is very strict, determined, and serious.

He always completes what he decides to do.

After losing his wife, he became even more committed to his beliefs and actions.

He wants Senya to be strong, sometimes making hard choices for him.

Jinun used to be known as "Kumozou" before he joined the Dankai Group.

He is a member of the Silver-Haired Clan.

He could not protect his wife, which is a painful part of his past.

This experience made him very strict and strong-willed.

He became the leader of the Four Beast Generals because of his great power.

Jinun is a modified human with the power of a "dragon."

He has spirit power ten times greater than Jinka Yamato.

He uses powerful moves like "Broken Army Palm," "Broken Army Twin Palms," and "God-Slaying Secret Technique: Demon Sea Dragon Dust Kick."

Jinun can fight against very strong opponents and is one of the most powerful characters in the story.

• Senya: His son. Jinun cares for Senya and wants him to be strong. He allowed Senya to be a test subject to give him more spirit power.
• Wife (Senya's Mother): Jinun loved his wife deeply and could not protect her. This loss changed him and guides many of his actions.
• Nadare: A dragon sealed inside Jinun. Nadare is also the uncle of Mudo. Their bond becomes important later in the story.
• Dankai Group: Jinun is the leader of the Four Beast Generals, one of the top groups in Dankai.

Early Life and Motivation

Before joining Dankai, Jinun was called "Kumozou." He decided to become stronger after losing his wife to an enemy he could not defeat. This painful experience made him promise never to fail again.

Giving Senya Power

Jinun agreed for his son Senya to be changed with spirit power, hoping to make him strong enough to defend himself and others. This showed how much he wanted to protect Senya, even if it meant making hard choices.

Battle and Sealing

In the first part of the series, Jinun fights Jinka Yamato, using his amazing spirit power and powerful moves. However, during the battle, the Mountain God ends up sealing both Jinun and Senya away.

Sealed Years and Return

Jinun remains sealed and out of sight for most of the second part. He only appears in Senya's memories until, after eight years, the seal is finally broken, and he returns.

Struggling with Nadare

After returning, Jinun wants to keep following his strong sense of justice. He battles Senya, but the mysterious people called the People of Nothing target Jinun's weak spot—his heart. The dragon Nadare, sealed inside him, takes control of his body, pushing Jinun aside.

The Duel and Jinun's Sacrifice

Under the control of Nadare, Jinun is ordered to fight Senya. However, Nadare prefers a match against Dōren and ignores those orders. After losing the duel against Dōren, Jinun suffers fatal damage. With his last strength, Jinun gives his spirit core to Senya, passing away in the process.

Nadare's Fate

Nadare is a dragon who was sealed inside Jinun and is Mudo's uncle. When Nadare takes control, he follows some orders from the People of Nothing but also keeps his own will—shown by picking up and holding Furuon's pipe. After Jinun's defeat, Nadare's spirit and Jinun's spirit core are both transferred to Senya. Together with Jakki (another spirit), they become Senya's guides and guardians.

Jinun was one of the strongest fighters in his world.

His power and choices had a big impact on the people around him, especially his son Senya.
