This article is about a/an ally/temporary rider in Kamen Rider 555.

Keitaro Kikuchi (菊池 啓太郎 Kikuchi Keitarō) is one of characters from Kamen Rider 555.


Keitaro is a young man that Mari and Takumi meet by chance not long after receiving the Faiz Gear. Keitaro and his family are dry cleaners and its his dream to make everyone in the world happy. As such, he lets Mari and Takumi stay with him and work at his family's dry cleaning business for room and board in hopes that he can encourage them to use the Faiz Gear for good. He also seem to have an allergy to Orphnoch, though he thinks he is allergic to people with bad hearts. This may have been proven as he didn`t show symptoms towards Takumi who is the Wolf Orphnoch. He exchanges cell phone e-mails with his penpal, Yuka, and becomes infatuated with her in real life, although he doesn't realize that they are the same person until later in the series.

In Kamen Rider 555: Paradise Lost, he briefly wore the Kaixa Gear, thanks to the Transform One-Shot serum that allows a non-Orphnoch to safely use it. But due to the effect of the serum, the Kaixa Gear is reduced to ashes.

D-Video Special: Kamen Rider 4

As mentioned by Kamen Rider 4, Takumi and all of his friends (except Naoya Kaido) died after the final episode of Kamen Rider 555. Keitaro is hypothetically mentioned as one of the casualties.

Ability perimeters

Once transformation is completed, the Kaixa Armor has several key features in its design to protect the user. Like all gears, the Kaixa armor manifests when the Kaixa Driver generates Photon Blood, a glowing substance generates the soft Sol Foam suit, Sol Metal armor, and Fullmetal Lung chest armor via traveling through the two yellow Photon Stream's lines that give Kaixa greater strength at the cost of speed. The steams end at the Photon Terminals at the gauntlets and Power Anklet greaves, the right Anklet having an Energy Holster that the Kaixa Pointer can be connected to. The helmet is unique due to its Global Feeler antenna to link up to Smart Brain's networks and the X Finder visor that gives Kaixa incredible vision to see in darkness, giving the illusion of a glowing eye, and a limited amount of x-ray vision.
