Shinobu is a 49-year-old kunoichi from Wano Country and a loyal retainer of the Kozuki family in the world of ONE PIECE. She is known for her strong spirit as a ninja and her unique ability, the Juku Juku no Mi, which lets her cause things to decay quickly or make people’s bodies mature instantly. Though famous as a beauty in her youth and called “Shinobu the Man-Killer,” she is now plumper and often plays up her mature charm. Shinobu has a funny mix of bravery and clumsiness because she gets scared of sharp objects and has trouble seeing clearly. Her story is closely tied to Wano’s major events, like helping Momonosuke and aiding Luffy’s crew. After a wild turn of events, Shinobu even gets her young figure back for a while, showing how unpredictable adventures can be!
Shinobu is a tall woman—standing at 180 cm.
Now, she has a plump, “auntie” look, but twenty years ago, she was known for her beautiful and curvy figure with twintails.
She was so stunning that she could rival beauties like Nami, Robin Nico, Kozuki Hiyori, Shirahoshi, and Boa Hancock.
Today, she wears a standard ninja outfit.
Her older appearance is so different that even former acquaintance Hanzo mistook her for someone else.
After an event involving Admiral Ryokugyu, she temporarily regained her youthful appearance and stunning figure again, but later rebounded back to her old shape.
Her design is inspired by Japanese celebrity Naomi Watanabe and also Tara from the manga "Jungle King Tar-chan".
Her attributes:
- Age: 49
- Height: 180 cm
- Blood type: F
- Birthday: October 23
- Zodiac: Libra
- Favorite food: Hanpen (a type of fish cake)
- Least favorite food: Boiled dishes
- Hobby: Beauty massage
- Image animal: Flying squirrel
Shinobu is loyal and passionate about serving the Kozuki family.
She calls herself "Watasu" and likes to show off her mature, "sexy" aura, though most people ignore her.
She doesn’t hesitate to scold men who doubt her beauty, sometimes using her ninja skills directly on them!
Despite acting confident, she gets flustered in certain situations, especially around sharp weapons or when her vision fails her.
Still, her friends trust her, and she always tries her best for her allies.
Shinobu comes from Wano Country and first served as an elite member of the Oniwabanshu under the Kozuki clan.
Her dream was to serve Oden Kouzuki.
After the death of the former shogun, she left the Oniwabanshu because they followed Orochi Kurozumi and let him rule harshly.
Shinobu became an outlaw and was chased by her former squad.
During Oden’s rebellion, she helped the Kozuki family but was spared when Oden lied to protect her.
At Oden’s execution, Shinobu bravely revealed the truth about Orochi to the people of Wano, changing their view of Oden.
She fought beside Kinemon and the others, supporting the Kozuki family for 20 years.
Shinobu is a skilled ninja.
She has:
- Intimidating close-combat moves (like her signature "Ninja Art: Ball-Crusher")
- Ninja tricks like "Giant Kite" for flying, "Smoke Escape" for vanishing, and binding techniques.
She eats the Juku Juku no Mi (Rip-Rip Fruit), giving her the power to make anything she touches rot quickly.
She can:
- Open holes in the ground for escape
- Make ceilings collapse
- Even mature a human body into an adult, but their mind stays the same and it can’t be reversed
However, Shinobu sometimes struggles in battle due to farsightedness and a deep fear of sharp objects.
The Past
Shinobu used to be a top agent for the Kozuki family and worked with Fukurokuju and the Oniwabanshu.
After Kozuki Sukiyaki’s death, when Orochi took control, Shinobu left her group because she couldn't accept them supporting Orochi’s evil rule.
When Oden Kouzuki tried to overthrow Kaido and Orochi, Shinobu sided with Oden.
After Oden and the "Nine Red Scabbards" were defeated and caught, Oden lied during his execution to make her look like an enemy so she could escape.
When Oden was executed and called a “fool” by the people, Shinobu revealed Orochi’s plot and Oden’s true pain, making the people see the truth.
She helped Kinemon and the others escape and fought to protect Toki when they were attacked by the Beast Pirates.
While Kinemon and others were sent 20 years into the future by Toki, Shinobu stayed behind to fight for the Kozuki in the present.
Wano Country Arc
Shinobu returns as an ally to the Straw Hats and teams up with Nami for spy missions.
When Kaido attacks Oden Castle with fire, she uses her Juku Juku no Mi powers to save Nami and the others from the rubble.
With Robin Nico, she helps with risky plans at Orochi Castle.
When the raid plan is leaked and many allies are captured, Shinobu suspects Law's crew, getting into a fight with Law.
She witnesses the tragedy of Tonoyasu’s (Yasuie Shimotsuki’s) execution and explains the effects of SMILE fruit to the Straw Hats.
On the day of the big raid, Shinobu stays behind to guard Momonosuke Kozuki, but is attacked by Kurozumi Kanjuurou, who reveals himself as a traitor and kidnaps Momonosuke.
Shinobu is freed by Kawamatsu and joins up with the other retainers to attack Onigashima.
On Onigashima, Shinobu and Nami are chased by Big Mom but reach the Live Floor safely.
With Sanji's help, she helps rescue Momonosuke and stays by his side for his protection.
She meets Yamato, is confused at first, but then accepts her as an ally after being saved.
When Kurozumi Kanjuurou appears and then Kaido attacks, Shinobu escapes with Momonosuke using her fruit to open a hole in the castle to flee.
After landing in Udon, she reunites with Luffy D. Monkey.
Momonosuke asks her to use her powers to make him an adult and, though she is reluctant, she agrees when he begs her with tears.
She rapidly grows his body to that of a 28-year-old but his mind stays the same.
At the end of the battle, Shinobu watches the new shogun’s speech in the Flower Capital.
Later, during a party, Admiral Ryokugyu attacks Wano and uses his powers to suck the nutrients from Shinobu, making her thin and beautiful again.
After recovering, Shinobu lets Tama become her apprentice.
However, in a later story cover, it is shown that Shinobu has gained her weight back despite training with Tama.
- She calls herself Kinemon's “sister.”
- Loyal retainer of the Kozuki family, especially to Oden Kouzuki and Momonosuke Kouzuki.
- Often teams up with Nami and Robin Nico for missions.
- Acts as mentor to Tama after the Wano Country arc.
- Has mixed feelings about the Oniwabanshu and Fukurokuju due to their betrayal.
- Shinobu uses the speech pattern "watasu."
- Her childhood dream was to serve Oden Kouzuki.
- Her ninja outfit from 20 years ago was made by Kinemon.
- Her design is based on Naomi Watanabe and the character Jane (from Tar-chan).
- Her body transformation is played for comedy, especially how quickly she rebounds to her old self.
- The use of the word "rot" about her fruit power is forbidden—the correct term is "ripen!"
- Her favorite food is hanpen, and she dislikes boiled dishes.
Shinobu is a fun and comic character, but she also has deep loyalty and courage.
She shows that being a ninja is not only about fighting, but also about heart, wisdom, and funny surprises in the world of ONE PIECE!
