Darya Nikitina (ダリヤ ・ ニキーチナ Dariya Nikīchina) is a character in the manga Dr. Stone. She was a doctor on board the International Space Station (ISS) alongside her husband, Yakov Nikitin. While in space, she witnessed the petrification of all human life on Earth's surface from the ISS.[1]


Darya had short, blond hair and lavender eyes. She had full lips and pale skin.[1]


Darya has been shown to be quite aggressive. She is very protective of her research, considering them like her babies.


Village Origins Arc

Darya is first seen greeting Byakuya, new astronaut. Their conversation is interrupted by Lillian who acts as a condescending diva and startles her husband, only for the ruse to be broken by Byakuya's burst of laughter. Later on, Darya and Byakuya playfully set the music in the spacecraft to only play Lillian's songs, much to the latter's embarassment. 

While on the ISS, she witnesses the huge beam of light engulfing the earth and is consequently shocked to see all of humanity turned to statues.[1]

Once Shamil, Connie and Lillian land on ocean instead of ground, Darya assures them they have enough oxygen supply for 9 hours. Shamil then replies that this time is their limit on staying inside the vessel. Darya then proposes that Byakuya, Yakov and her land as well and rescue them by boat. Yakov argues that the boat will be nearly impossible to acquire, with Byakuya saying that they will make a raft and swim for miles if they need to.

3 years later, she is present at Shamil and Connie's wedding along with the rest of her crew members, her husband and her children.[2]

She is last seen offering to go to mainland in order to get antibiotics for Connie, who has contracted pneumonia. Before she goes, she asks Byakuya and Lillian to take care of their children. Darya and her husband were lost at sea looking for a cure.[3]

Lillian Weinberg

Upon the arrival of Shamil, Lillian, and Byakuya on the ISS, Lillian and Darya became friends, having enjoyed mutually teasing Darya's husband, Yakov. Upon returning to Earth, the two remained close as Darya and Yakov settled down and had children of their own. They helped in Byakuya's attempt to give message for his son in the future. Eventually, Lillian became the caretaker of her and Yakov's children after they were lost at sea and died while attempting to make it to the mainland in search of antibiotics.
