"Yellow Buster!"
―Yellow Buster's roll call[src]

Yoko Usami (宇佐見 ヨーコ Usami Yōko) is Yellow Buster (イエローバスター Ierō Basutā) of the Go-Busters. She is a sharp-tongued and easily-tempered teenage girl. Her partner Buddy Roid is Usada Lettuce.

Character History

Gokaiger vs. Gavan

The youngest of the group. The three Go-Busters make their first appearance in Kaizoku Sentai Gokaiger vs. Uchuu Keiji Gavan: The Movie where they take on their predecessors' nemesis, Basco ta Jolokia, to make sure he didn't get the Galleon.


What happens when Yoko's "battery" runs out of juice to burn.

She gained incredible kicking and jumping power from an accident, and as such this is her Buster Power. Her powers have a trade-off however. Her weakness is that if she runs out of calories for her "inner battery" to burn, she will be unable to move. Thus, she compensates by eating lots of candy.

13 years ago, when Messiah was newly created, it trapped the scientists and Buddy Roids into a small room. Yoko was among the trapped, as her mother was one of the scientists. After the head scientist teleported the facility to a dimension in hyper-space, Yoko, Ryuji, and Hiromu, as well as the Buddy Roids, were left behind. The little girl broke down, distraught that she had lost her mother. It was here that Hiromu promised that he would bring their parents back.

Super Hero Taisen

Yoko was caught up in the Super Hero Taisen incident, along with her teammates. She took part in the final battle, before being ejected from her Buster Machine.

Super Hero Taisen Z

While waiting for her teammates at a barbecue, Yoko discovered a small robot called Psycholon. After repairing him, Yoko acted as his protector from both Space Shocker and Madou. She helped him to break free from their control.

Kyoryuger vs. Go-Busters

As her team failed to rescue Ryouga from Deboth, their next mission is to protect the Kyoryugers. They arrive where the Kyoryugers are and manage to escape from Neo-Grifforzer and Neo-Geilton as they split up. Later, Yoko and Amy fought Escape as she told them that Vaglass is part the plan of awaking Space War God Borudosu. Yoko let Amy escape to save Geki and Ryouga as she stays to fight Escape. She later meet up with her team, but they were too late as the Kyoryugers were brainwashed and enters the past to have the dinosaur extincted. Her team arrive at the Spirit Base as they inform Kuroki and Torin about the Kyoryugers' action. He then gives the Go-Busters a task to save Geki and Ryouga from Deboth, with Torin's assistance. As they arrive in the satellite, they were too late to save the Red warriors as they fought Deboth's Knights. Overpowered, they still continue fighting until J arrive. Much to their surprise, Jin appears as he reveals to them that he is also part of Vaglass' residual program as his data was stored in J. Her team fought back as they manage to destroy the satellite to restore the Dinosaur Sentai's Dino Hope. As Space War God Borudosu is awakened and the Dinosaur Sentais were having trouble fighting the monster, they were about to join, but Beet Buster gave them the Go-Busters Zyudenchi as this is his final thing to do before he disappears. They join the battle as they entered in Raiden Kyoryuzin and formed Tategami Raiden Kyoryuzin to finish off Space War God Borudosu.

Transformation and Roll Call

Ranger Key

The Yellow Buster Ranger Key.

Mobilates' Gokai Change announcement[src]

The Yellow Buster Ranger Key (イエローバスターレンジャーキー Ierō Basutā Renjā Kī) is a Go-Buster Ranger Key which was given by Yoko to the Gokaigers. As a yellow key, it is primarily used by Luka Millfy (Gokai Yellow).


Behind the Scenes


Yoko Usami is portrayed by Arisa Komiya (小宮 有紗 Komiya Arisa). As a child, she is portrayed by Kokoro Hirasawa (平澤 宏々路 Hirasawa Kokoro). Yoko was briefly portrayed by Katsuhiro Suzuki (鈴木 勝大 Suzuki Katsuhiro) in Mission 28: Beware of Chickens, when Sprayloid 2 caused her appearance to change into that of Hiromu, though Arisa Komiya still provided Yoko's voice.

As Yellow Buster, her suit actor is Yuichi Hachisuka (蜂須賀 祐一 Hachisuka Yūichi) whose previous role was Gokai Yellow in Kaizoku Sentai Gokaiger. Like many female rangers, her suit actor is actually male, Yuichi Hachisuka having had only a few male roles since starting as Change Phoenix in Dengeki Sentai Changeman. In Kamen Rider × Super Sentai × Space Sheriff: Super Hero Taisen Z, her suit actor was Jiro Uchikawa (内川 仁朗 Uchikawa Jirō).

Yellow Buster is notably the last female Ranger to be portrayed by a male suit actor, all heroines in succeeding series would be portrayed by female suit actors as Yuichi Hachisuka moved to portraying female villains.


  • Yellow Buster is the first Sentai Hero to be based on a lagomorph.
    • Her last name is one letter off from the word meaning rabbit in Japanese (being usagi).
  • She is the only Go-Buster with a Buddy Roid of the opposite gender.

Dub Names

  • In the Korean dub of Go-Busters entitled Power Rangers Go-Busters, which aired in South Korea, Yoko is renamed Raby, while she keeps her ranger name.
