Kohaku is a young woman who is a descendant of modern humans. She is Ruri's younger sister and the daughter of Kokuyo. She appears to be well known in her village due to her combative abilities, as both Kinro and Ginro were afraid of her. Kohaku excels at fighting, hunting, and general survival skills. She is a tomboy by nature, having little interest in more typical feminine activities and has little knowledge about them, although she does seem to enjoy some lavish clothing that was provided to her. She possesses a sharp instinct and intellect.

Kohaku is a kind young woman, caring deeply for her sickly older sister, willing to participate in the tournament for her hand in marriage just to protect her. This care extends to her comrades, and anyone she's loyal to. In addition to this, she has a reckless and hotheaded personality, often reacting in anger to being called a gorilla or lioness due to her strength and physicality. She also acts on her emotions at times, going against rational thought. She also has a bit of a teasing side, asking Chrome if he could fall for her to her resemblance to her sister.

After five years of harboring unspoken feelings, high-schooler Taiju Ooki is finally ready to confess his love to Yuzuriha Ogawa. Just when Taiju begins his confession however, a blinding green light strikes the Earth and petrifies mankind around the world— turning every single human into stone.
 
Several millennia later, Taiju awakens to find the modern world completely nonexistent, as nature has flourished in the years humanity stood still. Among a stone world of statues, Taiju encounters one other living human: his science-loving friend Senkuu, who has been active for a few months. Taiju learns that Senkuu has developed a grand scheme—to launch the complete revival of civilization with science. Taiju's brawn and Senkuu's brains combine to forge a formidable partnership, and they soon uncover a method to revive those petrified.
 
However, Senkuu's master plan is threatened when his ideologies are challenged by those who awaken. All the while, the reason for mankind's petrification remains unknown.

The second cour of Dr. STONE: NEW WORLD.
 
Years ago, astronaut Byakuya left behind precious materials in the belief that his son, the scientifically-gifted Senkuu, would one day find them. In the present, the Kingdom of Science's Kohaku and Ginrou have infiltrated the harem of the Petrification Kingdom’s leader with the help of Amaryllis, a local girl. At first, their mission progresses without a hitch. Unfortunately, an error enacted by Kohaku and Ginrou leads Minister Ibara and the Island’s strongest warrior, Moz, to identify the intruding duo as enemies.
 
Even worse, Moz tails Amaryllis when she returns to inform Senkuu of the news, discovering the scientist's secret hideout. However, Moz's agenda does not align with Ibara's—he wants to dethrone the minister and keep the petrification device for himself. If Senkuu plays his cards right, he could gain a powerful ally and win the war once and for all.
