To transform, a Kyuranger inserts a Kyutama, making the Changer announce the name of the Kyutama, then pushes it forward, towards the nozzle; then they flip the grip down, shout Star Change (スターチェンジ Sutā chenji), then pull the trigger of the blaster to transform.
- "Seiza Attack!"

To attack, a Kyuranger grips the Kyutama and pulls it backward like a joystick.
- "Seiza Go!"

- "(voyager name) Voyager!"
- ―Summoning announcement[src]
To summon the Voyagers, the Kyurangers push their Kyutama to their left, then press the red button on the side of the changer's hand grip. Afterwards, they are wrapped around a giant Kyutama that becomes their cockpits.
- "Seiza Docking!"

To activate a finishing strike, a Kyuranger grips the Kyutama and pulls it backward like a joystick two times. The group finisher is the All-Star Crash (オールスタークラッシュ Ōru Sutā Kurasshu). If all nine Kyurangers fire their All-Star Crash at the same opponent, the attack with create a multicolored blast that slams onto the opponent from above, and leaves a star shaped crater.
- "Seiza Control!"
- ―Controller stand by announcement[src]
After summoning the Kyuranger's respective Voyager, they then pull the black trigger to control the Voyager from the blaster by shifting the Kyutama in the required direction. This function has yet to be seen in the show, though Lucky was seen utilizing this function once with the Pegasus Kyutama in an attempt to tame Pega-san.
- The Seiza Blaster resembles the Gabrichanger from Kyoryuger, in that it's a wrist wraparound with a grip.
- The speech of the transformation standby of "Seiza Change" is punctuated so it sounds similar to the English phrase "Say the Change!" (Say Za Chenji!), which more or less is a prompt for the Rangers to say their Transformation Call.
- The Seiza Blaster has some similarities to past Core Ranger Transformation Devices the Transformation Gun Gaburivolver from the 37th Super Sentai Zyuden Sentai Kyoryuger, The Transformation Brace ToQ Changer from the 38th Super Sentai Ressha Sentai ToQger, And the Transformation Ninja Sword Ninja Ichibantou from the 39th Super Sentai Shuriken Sentai Ninninger.
- Its similarities with the Gaburivolver is that both are Transformation devices that also act as firearms and can also be used by an Extra Ranger (even if its just one).
- Its similarities with the ToQ Changer is that both are wrist mounted Transformation Devices that also allow them to summon the Rangers Mecha.
- Its similarities with the Ninja Ichibantou is that both are Transformation Devices that also act as the Rangers sidearm and allows them to summon their Mecha and utilize a Finishing Attack.
