In the grand tapestry of Dr. STONE , a manga and anime series that glorifies human ingenuity and the relentless march of science, it is easy to be dazzled by the pyrotechnics of Senku Ishigami’s intellect or the raw power of Tsukasa Shishio. Yet, woven into the fabric of the series’ second major arc—the “Age of Exploration” and the journey to the other side of the petrified world—is a character of quiet but profound importance: Igarashi Natsu. Often affectionately called “Soyuz” by fans (a reference to his ersatz role as a Soyuz spacecraft commander), Natsu is more than just a brawny crew member. He is the living conscience of the new stone world, a bridge between the primal fear of the unknown and the scientific courage required to face it.
Born on July 8, 1998 , in Kyoto, Japan , Igarashi entered the adult film industry at the age of 23.
She is widely recognised for her 163 cm height and "E-cup" bust, with official measurements typically cited as B88-W60-H88 .
. Connecting with the Digital Audience In the age of social media, Natsu has built a significant following. Her Instagram Reels and TikTok showcases provide fans with a more personal look at her life and behind-the-scenes moments. This digital presence has helped her cultivate a fanbase that spans far beyond Japan, reaching audiences who appreciate both her aesthetic and her dedication to her craft. What’s Next for Natsu? As of 2026, Igarashi Natsu continues to be a central figure in her industry, frequently releasing new works through major labels like FALENO .

Igarashi Natsu is the soul of Dr. STONE ’s second half. He is the reminder that beneath the blueprints and the chemical reactions, science is a human story. It is the story of children waiting for their parents, of communities preserving stories, and of frightened young men finding the courage to face the cosmos not because they are unafraid, but because they love. In a series that often celebrates the cold logic of the laboratory, Natsu stands as a warm, beating heart—proof that the most essential element for rebuilding civilization is not just intelligence, but empathy. He is, without question, the most human character in a world of stone.
