Description
Kori is a fourteen-year-old boy with red hair who serves as the main protagonist of the anime Shin Hakkenden. His background is set in a distant future where humanity fled a destroyed Earth and now resides across eight moons. He sets out on a deeply personal journey to find his mother, a search he believes will unlock the truth about his own origins and the power he wields. Kori comes into possession of a powerful sword forged by his father, a weapon given to him by Kou Yagami. The sword holds a red gem embedded in its hilt, which is the source of his most defining ability.

Kori possesses a fundamentally good and generous soul. He deeply values loyalty and tries to show compassion even to those hardened by violence. Despite his kind nature, he is plagued by intense internal conflict because the red gem can transform him into the invincible warrior known as the Shin Hakkenden. This transformation grants him immense power but causes him to lose his reason, turning him into an uncontrollable force. When he regains consciousness and sees the destruction he has caused, he is overwhelmed by guilt and inner turmoil, creating a constant struggle between his peaceful intentions and the destructive means he must use.

His motivations are driven by his quest for his mother, a desire to understand the secret of the gem and his sword, and a strong urge to protect the innocent from the oppressive forces corrupting the eight moons. He actively joins a guerrilla resistance and personally intervenes in local conflicts, such as when he attempts to save a village from the powerful cyborg Gokumon.

In terms of relationships, Kori gains a steadfast ally in Kujo, a talking cyborg dog with an eyepatch who also carries a jewel embedded in his tooth. Kujo becomes a faithful companion who helps him overcome many hardships. Kori also forms a complicated bond with Nola, a cynical and cold girl who was forced into a life of violence. Despite their initial violent clashes, Kori’s unwavering good heart leads him to try to teach her the value of trust and loyalty.

Kori’s development throughout the series centers on mastering his transformation. He begins unable to control the power of the gem, and his character arc is defined by learning to balance his immense strength with his conscience. By the climax of the story, he finally succeeds in fully controlling the gem's power, allowing him to fight effectively as one of the eight chosen warriors. His notable ability remains the transformation triggered by the red gem, which grants him superhuman combat skills and defines him as the legendary warrior of the title.
