 is Buster's black tortoise-based primary form accessed by using the Genbu Shinwa Wonder Ride Book in the Dogouken Gekido.
Compared to Saber and Blades, Buster has higher punching power and kicking power than the two, but due to its heavy armor, his running speed and maximum jump height is significantly low.
Genbu Shinwa consists of the following parts:
*: The helmet.
**: The blade on the forehead. It is installed on the top of the head as a proof of being selected by a Seiken. It has the role of adjusting the state of Kamen Rider Buster and the Seiken, and adjusts the power balance between them and cancels transformation in an emergency. It is also a blade with a sharp edge, and can also be used in battle.
**: The visor. It allows the user to gaze at those who oppress the weak.
**: The audio protectors. It stabilizes the the body's position and functions as a motion balancer that suppresses the loss of behaviour and attacks when maneuvering a large sword or performing a high-power attack.
**: The facial armor. It is covered with armor that protects the user from all kinds of disasters, with the power of the God Beast "Genbu Shinwa". In addition, he is good at head-butting by taking advantage of its hardness.
*: The chest armor. The armor that protects the user from all kinds of attacks, which has the power of the God Beast "Genbu Shinwa", which solidifies the whole body. Furthermore, by arranging the "Gorikikko" generator in each joint, increasing the user's durability.
*: The suit granted by the user of the Seiken "Dogouken Gekido". It is attached at the same time as the awakening of the Seiken, and gives the user the power to fight such as improving sword skills, strengthening physical abilities, and activating special abilities. Based on the form with the power of the Wonder Ride Book "Genbu Shinwa", various abilities can be added by additionally scanning the Wonder Ride Book.
*: The arms. The role is different between the right side, which specializes in swashbuckler attacks, and the left side, which supports it and provides stronger defense. In addition, the armor "Sword Robe" enhances the physical strength and the overwhelming power generated by the cylindrical rigidity generator makes it possible to handle heavyweight swords that are difficult to handle.
*: The gloves. Holds the handle of the Seiken firmly by strengthening the user's grip strength. It also functions as an ability transmission road that connects the Seiken and the "Sword Robe" to convey the power of the Seiken and the abilities of the Wonder Ride Book.
*: The legs. It makes various attacks by stepping on the ground powerfully like the God Beast "Genbu Shinwa" and stabilizing the upper body. In addition, the exterior of the armor "sword robe" has been adjusted with the highest priority on durability in order to correspond to the battle style that emits high output, which is the specialty of Buster.
*: The boots. It is heavily armored with the armor "Bushin Gora" and can handle any terrain. Also, when the Special Move is activated, it shoots a heavy blow like a giant mountain with the power of Wonder Ride Book.
*: Storage for extra Wonder Ride Books. Mounted on the back of the Sword of Logos Buckle, it can hold two books on the right and one on the left.
This form has two finishers:
*Rider Slash: : When Buster scans one book, Buster can execute a rider slash based on the book.
**Genbu Shinwa: Surrounding rocks gather onto the Dogouken Gekido, massively enlarging the sword and generating energy on the blade part allowing Buster to perform an enhanced downward / horizontal slash.

*The two Kanji in his name, "Kame" (亀) and "Mi" (巳) are both related to Kamen Rider Buster's basis on the : "亀" means "Turtle" and "巳" is associated with Year of the Snake in Chinese culture.
**As with the surname scheme of other members of Sword of Logos, The "Kami" in Kamikawa is a homophone of meaning "god".
