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

Her unofficial role in the Kingdom of Science is the disciplinary, as she is constantly shown keeping idiots like Magma and Yo in line; she's hurt them numerous times when they attempt to do something violent or shortsighted.

She is a member of the Power Team.


Nikki is a considerably tall young woman with a slim, but curvy and well-muscled figure with a rather impressive bust size. She has blonde hair that is braided into two ponytails which come down to her shoulders and are tied at the ends with a blue bow. She has round, expressive eyes with large lips and an average sized nose. Her attire consists of a crude green dress with a U neckline that shows her impressive cleavage, that splits at her hips, with a sash belt wrapped around her waist that holds two bat-like clubs, and cloth shoes.

After she is de-petrified again in the Petrification Island Kingdom, her outfit remains as a crude green dress with split hip ends, but now it has a corset design on the stomach region, with the top being replaced by a V-neckline bikini with a fur neck, and on her hips fur tussles held on by two metal plates, and on the back is a leather belt-like holster for her bat clubs.

Like most modern timers, she has a petrification scar on her body but it is unknown where. She later recreates her unknown scar, as a sign of loyalty to Senku.[5]



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 Lilian's song, she quickly changes side from Tsukasa's army to Senku's Kingdom of Science to help protect it.

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 kneeing Magma severely (and comically) in the crotch for stating she didn't count as a beauty (though, she did agree with him). In addition, despite her strength, she is actually extremely feminine. While making cloth for the hot air balloon, she suggested dyeing it in many different colors. In addition, when writing captions on photographs, her handwriting was so girly and cute people mistook it for Mirai's at first (before she corrected them). She also demonstrated desire for more girly clothing once Yuzuriha began mass producing fashionable modern clothing.

Gen has also pointed out that she is perhaps the purest maiden there is, since when she was asked to fake being in love with Hyoga to try and convince him to fight alongside them, she got flustered at the idea.

Physical Abilities

She is shown to be very physically strong, like smashing concrete with a hammer to make roads.

Lillian Weinberg Trivia

As a devoted fan of Lillian, Nikki possesses encyclopedic knowledge of Lillian factoids. Nikki comes very close to foiling Senku and Gen’s plan to imitate Lillian and demoralize Tsukasa’s army by asking them for statistics, forcing Senku to make complicated logical guesses to satisfy her. She later tutored Gen on the finer aspects of Lillian’s voice to further perfect their ruse.

Nikki's stats, according to Volume 8


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.


Village Origins Arc

She briefly appears watching Lilian's performance in space.

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.[6]

Senku requests that Taiju and Yuzuriha bring a member of the Tsukasa Empire 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.

She punches Taiju for every four letters he says, until he convinces her to come with them. When she heard Gen's Lillian impression, she decides to quiz them on her CD sales and later her measurements. When they get the measurements wrong, Senku plays a recording of her music to convince her they are the real thing. She sadly realizes Lilian is dead and decides to defect after Senku promises to protect the last record of her singing.[7]

After defecting, she decides to coach Gen on how to improve his Lilian impression.[8]

Age of Exploration Arc

On Senku's command, she and the Power Team dug up Ryusui and the other petrified sailors.[9] She later aids in making roads.

Treasure Island Arc

She is petrified by Ibara and his forces. She is depetrified alongside Magma and Kinro.[10]

New America City Arc

She takes part in the voyage to America, mostly being in the background.

She is later present at the poker game between Senku and Ryusui on which route should be taken.[11]

During the game, she notes that with Ryusui and Gen's strategy, Senku would have to win with a flush but notes on the impossible feat.[12]

After the recreation of beer, she is confused by a Ryusui being upbeat before it is revealed there is a casino.[13]

She holds Magma back after Dr. Xeno insults him. She is later shocked to see a plane flying over the Perseus. She remarks they shouldn't have assumed the enemy had a second one.[14]

As the battle between Stanley, Senku, and Ryusui took place. When the Perseus came under attack, Nikki and her group were confronted by Stanley's unit. A large female soldier charged at them and was able to subdue them.[15]

Nikki was later rounded up, along with her friends by Stanley's unit. However, Mozu and Matsukaze remained free and she watched as the two held their own, in spite of the enemy using guns and grenades. However, they were ultimately beaten by Stanley Snyder.[16]


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.

Gen Asagiri

After defecting, she tutored Gen on his Lillian Weinberg impression.


  • 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".
