The Chronicle of the Stone World: Unveiling the Ages, Heights, and Birthdays of Dr. Stone’s Main Cast

In a world petrified for millennia, the brilliant mind of Senku Ishigami awakens to a new age, a stone world where he must rebuild human civilization from scratch. At the heart of this grand scientific adventure is a diverse and memorable cast of characters, each with their own unique strengths and personalities. While their roles in the Kingdom of Science are well-documented, the personal details of their ages, heights, and birthdays often get lost in the whirlwind of scientific discovery and high-stakes battles. A closer look at the official data provides a fascinating glimpse into the human element of this post-apocalyptic saga, revealing key details that add depth to their relationships and development throughout the series.

The petrification event, which occurred in the year 2019, fundamentally altered the timeline for the entire human race. As such, the characters’ ages are often cited in two ways: their chronological age before being turned to stone, and their biological age, which reflects the years that have passed since the petrification. The story of Dr. Stone, which begins on April 1, 5738, takes place over several years, meaning the characters’ ages change throughout the narrative. Here, we break down the key figures of the Dr. Stone universe, providing a definitive guide to their physical and chronological attributes.

The Kingdom of Science: A Team of Ten Billion Percent

• Senku Ishigami
  • Age: 15 (pre-petrification). By the time of the Stone Wars, he is biologically 17, and by the end of the manga, he is at least 23.
  • Height: 5’7″ (171 cm)
  • Birthday: January 4, 2004
  • Senku’s unwavering belief in science is the driving force of the entire series. His age is a crucial plot point, as he was a high school student when the world ended, yet his incredible intellect allows him to lead a new civilization.
• Taiju Oki
  • Age: 16 (pre-petrification). He is around the same age as Senku, with his age also increasing as the story progresses.
  • Height: 6’2″ (187 cm)
  • Birthday: April 2, 2003
  • Taiju is the brawn to Senku’s brain. His immense physical strength and unwavering loyalty are essential for the survival and progress of the Kingdom of Science, particularly in the early days.
• Yuzuriha Ogawa
  • Age: 16 (pre-petrification), the same age as Taiju.
  • Height: 5’3″ (161 cm)
  • Birthday: June 1, 2003
  • Yuzuriha’s role as the group’s craftswoman and designer highlights the importance of art and skill in rebuilding society. Her patience and kind nature are a vital counterpoint to the more impulsive characters.

  • Age: 18 (pre-petrification), making him older and more experienced than Senku.
  • Height: 6’5″ (195 cm)
  • Birthday: October 10, 2001
  • Known as the “Strongest Primate High Schooler,” Tsukasa’s age and physical prowess are central to his ideology. His desire to create a world free from corrupt adults makes him a compelling antagonist.
• Kohaku
  • Age: 16 (at her introduction). Her age is based on the Stone World’s timeline.
  • Height: 5’3″ (160 cm)
  • Birthday: August 8, 5723

• Chrome
  • Age: 16 (at his introduction). He is the same age as Kohaku.
  • Height: 5’7″ (170 cm)
  • Birthday: February 4, 5723
  • A self-proclaimed sorcerer, Chrome is the perfect foil for Senku. His passion for discovery and his homegrown knowledge of the Stone World are vital for the Kingdom of Science’s success.
• Gen Asagiri
  • Age: 19 (pre-petrification). He is one of the oldest main characters from the modern world.
  • Height: 5’9″ (175 cm)
  • Birthday: April 1, 2000
  • As a mentalist and master manipulator, Gen’s true value lies not in his physical strength, but in his cunning intellect. His experience as an adult in the modern world gives him a unique perspective on human nature, which he uses to his advantage in the Stone World.

The details of these characters’ ages, heights, and birthdays add a layer of realism to the fantastical world of Dr. Stone. They highlight the youthful ambition of its protagonists and the weight of their legacy, reminding us that even in a world without technology, the human spirit—and the quest for knowledge—is what truly matters.
