Vinsmoke Reiju

"Poison Pink" Vinsmoke Reiju is a member of the Vinsmoke Family and Germa 66. She is Sanji's and Yonji's older sister.

Appearance
Reiju is a young woman with shoulder-length blonde hair that covers her right eye. Like her siblings, her eyebrows are curly. She wears a dark dress with a split in the center going down to her stomach, as well as target symbols on her forearms and her breasts. She wears dark gloves, a pair of headphones with the number 66 on them, and has the number 6 tattooed on each of her upper legs.

Personality
Unlike her callous brother Yonji, Reiju is civil, especially to people who have helped her family members. She also sometimes acts flirtatiously with men, like with Luffy.

Abilities and Powers
Due to being a member of the Vinsmoke Family, Reiju possesses great political power, although the extent of that power is currently unknown.

She seems to be proficient in kicking, as she kicked her brother Yonji off of a ship and into the sea, despite Yonji attempting to deflect her.

Poison Pink
Reiju possesses an ability that has given her the name "Poison Pink." She is capable of sucking poison out of people through mouth-to-mouth contact and putting it into her own body, and she will suffer no ill effect from the poison.

Equipment
Due to her family's technological prowess, Reiju possesses high-tech objects, one of which allows her to leap large distances.

Whole Cake Island Arc
Reiju first encountered the Sanji retrieval team right after they entered Big Mom's waters. When her brother, Yonji, taunted Luffy's group to try to take the antidote to Luffy's poisoning by force, Reiju kicked Yonji for his rudeness. She then boarded the Thousand Sunny and introduced herself. Reiju then cured Luffy of his condition by sucking the poison out of him. With Luffy's life saved, Reiju thanked the crew for taking care of Sanji. Reiju and Yonji then left the Sanji retrieval team alone without making a scene. They also decided to pretend that they never saw the Straw Hats to prevent Sanji's marriage from being called off.
