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 people like Magma and Yo in line, stopping them from doing violent or shortsighted things. She is also a member of the Power Team.


Nikki Icons.png

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.[8]


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.

Abilities and Skills

Physical Abilities

  • Great Strength: She is shown to be very physically strong, like smashing concrete with a hammer to make roads. She is also capable of carrying a large man like Magma and Yo.
  • Judo: In high school, Nikki was recruited by the judo club because of her brawny build. She spent her school days training hard until she was black and blue from bruises, and earned the nickname 'boss' from her underclassmen.[9]

Mental Abilities

  • 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.
  • Linguistic Proficiency: She states as a fan of Lillian Weinberg that she had to learn English to understand her lyrics. However, she is mentioned to be fluent in broken English. Regardless, she was able to understand and communicate with Dr. Brody during their negotiations for the establishment of Corn City.[10]

Nikki's stats, according to Volume 8


Throughout her childhood, it seems that Nikki had been bullied by her peers for being so butch. Listening to her idol, Lillian's, songs is what was able to get her through her rough school life, so much so that she says Lillian saved her. Because of her vast love for Lillian's music, Nikki became a super fan, picking up all sorts of trivia and knowledge. She remembered every detail of Lillian, from how many CDs she's sold, to her southern accent. Nikki has listened to Lillian so many times that she's immediately able to tell the CD is real from just a few seconds[11]. At some point when she was young, Nikki attended a concert of Lillian's, and was so moved she cried, much like with many of Lillian's songs[12].

At some point in her school life, Nikki is recruited by the Judo Club at her school, because of her large build. It's said she spent every day of her school days training until she was bruised and cut all over. In the worker file, it is stated that her underclassmen called her boss. Despite how tough and brawny Nikki looks to people, she's affectionate deep down. The week before the petrification would hit, Nikki was shown watching Lillian's live performance from the ISS, her hands were bruised and plastered so it can be assumed this was just after one of her training sessions at the Judo Club.

Nikki would later be petrified in 2019 along with the rest of the world, although it is unknown where she was or what she was doing at the time it occurred.


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.[13]

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.[11]

After defecting, she decides to coach Gen on how to improve his Lilian impression.[14]

Age of Exploration Arc

On Senku's command, she and the Power Team dug up Ryusui and the other petrified sailors. Although she was worried about what he would be like after Minami describes him. However, Senku revives him anyway, to her shock.[15]

She later aids in making roads.

Treasure Island Arc

She is petrified by Ibara and his forces. She is depetrified alongside Magma and Kinro.[6]

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.[16]

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.[17]

After the recreation of beer, she is confused by a Ryusui being upbeat before it is revealed there is a casino.[18]

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.[19]

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.[20]

Nikki was later rounded up, along with her friends by Stanley's unit. However, Moz 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.[21]

Nikki overhears Senku making a deal with Dr. Brody by telling him of the revival fluid to establish Corn City.[22]

As this goes on, Nikki and the others converse with her telling Yuzuriha that she knows some English to communicate with the American Colony. When Brody tries to make conditions with Minami, Nikki speaks up and her fierce nature leaves him so impressed that he agrees .[10]


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 is shown to often keep Magma in check, such as when she hit him hard on the head when he charged in with the gun they made, after which she teased him and told him to do his worse.
