Kinrou is the elder brother of [Ginrou](https://anilist.co/character/143270/Ginrou) and the son of Tetsuken and Shirogane. Originally having served as one of the guards of Ishigami Village alongside Ginrou, he quickly joined Senku as a member of the Kingdom of Science. 

Kinrou is a muscular young man of average height, with a scar on the right side of his face and a cluster of hair hanging in between his eyes. He wears a sleeveless karate gi-like uniform with a belt and a buckler with a star pattern on his back. After the Grand Bout, Kinrou begins wearing a pair of glasses to correct his nearsightedness.

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.
