Sakura Nishihori

"The Deep Adventurer! Bouken Pink!"

- Bouken Pink's roll call

Sakura Nishihori (西堀 さくら) is the Deep Adventurer Bouken Pink (深き冒険者ボウケンピンク) of the Boukengers.

Boukenger
The sub-instructional person on the team, she was a former Self-Defense Force official, and she was raised as an elite of combat. She is also good at handling machines, shooting, and military arts. She is a little bossy, as seen in Task 1. She refers to Satoru Akashi as "Chief." Sakura is often seen as the serious, level-headed person in the group and barely ever smiles. She soon gets along with Natsuki Mamiya and starts trusting her more, contrary to the beginning of the series where she threatened Natsuki with a sword, believing her to be part of the Negative Syndicates. Sakura is very loyal to SGS and keeps her feelings for Satoru to herself. She and Souta Mogami frequently fight Shizuka of the Wind. In the movie, Sakura is also revealed to have a fear of bugs.

In Task 26, it is revealed that she ran away from her parents and joined a special army school to find her destiny, and when she first met Satoru and he asked her to join the other Boukengers in the shooting gallery. She may seem very cold-headed and insensitive to a certain point but in Task 31, after Eiji Takaoka was badly injured by Furious Demon God Gai, Sakura's emotional self showed after being enraged by the cruelty and treachery of Gai. After the final battle with Arch Priest Gajah, Sakura stowed away on GoGo Voyager when Satoru left the Boukenger team to take on a new adventure in outer space with her new-found treasure: her smile.

This also marks the point when, for the first time in the series, Sakura calls Satoru by his real name, and not by "Chief." In the finale, Mister Voice tells Sakura not to give up on Akashi (as Akashi is obviously oblivious to Sakura). However, while exploring planet Isla, Sakura is possessed by the released Pachacamac XII, who uses her as both a host and as a hostage to ensure Satoru aids him willingly in gaining his ancestor's power. Once freed of the monster's control, Sakura aids her team and the Gekirangers in defeating Pachacamac.

Ranger Key
The Bouken Pink Ranger Key (ボウケンピンクレンジャーキー) is Sakura Nishiori's personal Ranger Key and what became of her powers after she along with the rest of the 34 Super Sentai sacrificed their powers to end the Great Legend War.

This key along with the majority of the Ranger Keys were collected by the Red Pirates and later used by the Gokaigers. The Bouken Pink Ranger Key was mainly used by Ahim de Famille (Gokai Pink), who used it to fight as Bouken Pink. It was also used by Luka Millfy (Gokai Yellow) on one occasion.
 * When the Gokaigers became the Boukengers in their battle with the revived King Ryuuwon.
 * Luka became Bouken Pink as part of an all-pink Gokai Change in the Gokaigers' fight with Makuu Prison Chief Ashrada.

The Boukenger keys, along with all the Ranger Keys of the first 33 Super Sentai, were briefly taken by the Black Cross King and turned into Ranger puppets that were fought by the Gokaigers and the Goseigers. Splitting up, the puppet Bouken Pink was defeated as part of a group of surviving Pink and White warrior keys by Gokai Pink and Super Gosei Pink.

After Zangyack were finally defeated, the Gokaigers gave the Ranger Keys back to their rightful owners. Sakura received her key and became Bouken Pink once more.
