Nikki ( (はな) () () () Hanada Niki) is a survivor that was revived by Tsukasa. She later defected from the Empire of Might and joined the Kingdom of Science.


She has blonde hair that is braided into two ponytails which come down to her shoulders and are tied at the ends with a bow. She has unusually large lips and an average sized nose.



Nikki is fiercely devoted to Lillian Weinberg. It is implied that in the modern world she was having a rough time at school and listening to Lilian's songs saved her. When she listens to Senku's broadcast, she is able to tell through Gen's disguise of Lilian due to having a wide knowledge of trivia facts about her. However, once Senku states he has the final surviving copy of Lilians' song, she quickly changes side from Tsukasa's army to Senku's Kingdom of Science. Like Kohaku, she is quite strong for a woman and is shown to handle a great deal of the physical work alongside Kohaku, Magma, Taiju, and Yo. While seemingly proud of her strength, she gets annoyed when others point out her lack of femininity, at one point punching Magma severely (and comically) for stating she didn't count as a beauty. In addition, despite her strength, she is actually extremely girly. While making cloth for the hot air balloon, she suggested dying it in many different colors. In addition, when writing captions on photographs, her handwriting was so girly and cute people mistook it for Suika's at first (before she corrected them). she also demonstrated desire for more girly clothing once Yuzuriha began mass producing fashionable modern clothing.

Not much is known about Nikki's past, but she has stated that she had rough times during her school days. She was also (and still is) a huge fan of the now late Lillian Weinberg.

Along with the rest of humanity on Earth, Nikki was turned into stone.


Communications Arc

Nikki was on surveillance duty on watching both Taiju Oki and Yuzuriha Ogawa, as ordered to by Tsukasa. Her presence was noticed by the two while they were standing by Senku's "grave". Taiju began screaming Senku's name, which Nikki assumed was him grieving, completely unaware that there was a communication device buried under the grave. Senku requests that Taiju and Yuzuriha bring a member of the Empire of Might to the grave in order to go through with their plan of deceit. Without any thought, Taiju instantly turns to Nikki and asks her to hear him out.


Tsukasa Shishio

The one who revived Nikki. Initially, she was loyal enough to follow any orders given by him. Though, it seems that she wasn't fully devoted on serving Tsukasa, as she easily changed sides to the Kingdom of Science.

Senku Ishigami

During her alliance with Tsukasa, Senku was initially an enemy to Nikki. However, when Senku played Lillian Weinberg's song through the communication device, she was easily swayed. When Senku promised to never let Lillian's legacy burn out, she claims to have fallen for him, much to Senku's discomfort.


  • Nikki's full name is composed of "ni" ( virtue) and "ki" ( princess), with her nickname Nikki also being an alternative reading of the name, and her last name "hana" ( flower) and "da" ( field) creating "flower field".
