In the expansive world of One Piece, Oda has introduced several memorable side characters with unique backstories and intricate development. Vinsmoke Reiju is one such character, playing a key role in the Whole Cake Island Arc and sharing an important relationship with her brother. So, who is Reiju in One Piece?

Vinsmoke Reiju, also known as Poison Pink, is Sanji’s elder sister who was one of the few kind people to him growing up. She is the princess of the Germa Kingdom and a commander of the Germa 66 army, playing a crucial role in the series. Let us take a closer look at this.

Who Is Reiju in One Piece?

As the eldest child of Vinsmoke Judge, Reiju seemed apathetic at first glance but was compassionate and caring deep down. Her epithet, “Poison Pink,” comes from her ability to absorb and neutralize toxins, which defines her fighting style.

Similar to her siblings, Reiju had faced the modifications of her father and gained great strength. While she received his pride for this reason, Reiju was far from her egotistical siblings. She realized the faulty authoritarian ways of her family and the treatment that Sanji went through.

Nevertheless, she mainly expressed her views in secrecy, not openly sharing them for fear of retribution. As one of the few who allied with Sanji and the Straw Hats right from the get-go, this figure of resilience and grace is a hugely compelling character in the series.

Reiju’s Relationship with Sanji

Reiju’s relationship with Sanji is a highlight of One Piece. Growing up, Sanji had been heavily bullied by his own family, while Reiju joined them and seemed to be happy. However, she later revealed that she truly cared about her brother. She tended to his injuries, providing him relief while sharing that she only joined her brothers to not be bullied herself.

To help Sanji escape mistreatment, Reiju aided his departure from the Germa Kingdom, knowing he’d find happiness elsewhere. Even when Sanji reunited with his family at Whole Cake Island, she cared for him and celebrated his growth.

At the time when Big Mom’s plan of betrayal was identified, Reiju encouraged Sanji to abandon them, believing it was what they deserved. However, Sanji still couldn’t forget his familial bond, particularly the love he had for Reiju. Due to this, he crashed the party and ended up saving her.

Hence, despite being a loyal member of the Germa army, Reiju’s actions underscore her deep care for Sanji’s well-being, even at the risk of her own safety. Sanji’s kindness can be heavily attributed to his sister, who was a ray of sunshine to him during a dark time.

Reiju’s Strengths and Abilities

Having gone through several genetic enhancements, Reiju is a physically superior being to most humans. She was strong enough to bend steel as a child and is extremely fast and durable. As mentioned earlier, her name Poison Pink comes from her affinity for poison.

She is resistant to most of these toxins, sucking them out of a poisoned Luffy and saving his life. By combining it with her attacks, they can also cause immense damage on the battlefield. Her poison-based abilities give her knowledge in medicines, where she can rapidly assess injuries and treat them.

Additionally, Reiju is a very important figure in the Germa Kingdom. She possesses their powerful raid suits and has command over the army. Her willpower, which was strong enough to withstand Supreme King Haki, makes her a force to be reckoned with.

Reiju played a key role in the Whole Cake Island Arc, where the Vinsmoke family became involved in Big Mom’s plans. Though happy her brother had returned, she noticed his inner turmoil and Luffy’s efforts to rescue him.

Hence, after figuring out Big Mom’s plans to assassinate the Vinsmokes for the technology, she provided crucial information to Sanji to let him escape. As the arc proceeded and Reiju and her family were under the threat of Big Mom, the Straw Hats refused to abandon them and came to their rescue.

Acknowledging Sanji’s new friends, the Vinsmokes repaid them, with Reiju rescuing Nami from Charlotte Smoothie. She put up a valiant fight against the Big Mom Pirates using her poison abilities, risking her own well-being to finally let Sanji and the Straw Hats escape Totto Land.

Reiju and her family were injured at the end of the Whole Cake Island Arc, having incurred Big Mom’s wrath for assisting the Straw Hats. However, fans were relieved to see that she was still fine through the One Piece cover story – Germa 66’s Ahh… An Emotionless Excursion.

In this, she worked with Ichiji to free her siblings from Whole Cake Island, saving Caesar Clown in the process. With the help of his poisonous gas, they caused chaos among the remaining Charlotte siblings while safely escaping to Saint Germain. Here, her father and Caesar reached an understanding, forming the research institute NEO MADS.

Hence, Reiju is still alive and well, helping the Germa Kingdom pick up its feet. However, following their fight with Big Mom, fans are expecting the Vinsmokes to take a less toxic approach, possibly even allying with Sanji in the Final Saga.

Conclusion

Vinsmoke Reiju is a character who embodies strength, compassion, and resilience. Her role in the One Piece narrative, particularly during the Whole Cake Island Arc, showcases her importance as both a sibling to Sanji and a key member of Germa 66.

As one of the few positive figures in Sanji’s life growing up, fans will be hoping for the brother-sister duo to reunite before One Piece concludes.
