Shin Kazamatsuri (風祭 真) is Kamen Rider Shin (仮面ライダーシン) and the main protagonist in the Japanese tokusatsu movie Shin Kamen Rider: Prologue.

Biography
Shin Kazamatsuri is a motorcyclist who gave everything up to volunteer for his father's experiment, not knowing the true ambitions of his father's partner or the organization they worked for. He struggles to uncover the conspiracies, not completely knowing just how much his loved ones are truly involved. He overcame many enemies and learned how to control his mutant form, but was filled with sadness because of the death of his girlfriend, his friends, and ones who had helped him in escape from the FBI and the Syndicate who hunted him.

In the end he fought Cyborg Soldier Level 2 and when he tore off the monstrous humanoid's head, it had a bomb in it. Shin quickly threw the head and after a short final confrontation with FBI and The Syndicate, he takes his girlfriend's body and surprisingly his child inherits his mutation, causing Shin to be able to communicate to his child. Shin smiles and takes his girlfriend's body, following the light that guided him from the child.

All Riders vs. Dai-Shocker
Shin, along with every other Showa Rider, appears in Kamen Rider Decade: All Riders vs. Dai-Shocker. In the Internet spinoff films accompanying the movie, Shin is identified as the 13th official Kamen Rider of the Showa era. During the battle, he is seen fighting Bakeneko, Formica Pedes, Rat Fangire, Shiomaneking, Mole Imagin and Geophilid Worm.

Let's Go Kamen Riders
A mishap caused by the Greeed Ankh unintentionally altered the timeline which enabled Shocker to utilize a Cell Medal to create the Shocker Greeed which defeated the Double Riders and seemingly erased the legacy of the Kamen Riders from history. In 2011, after Kamen Rider New Den-O's attempt to repair the damage, he along with Kamen Rider OOO and M-Ankh awaited execution. However, it was revealed the Double Riders had their brainwashing removed by a Shocker scientist.

The Double Riders joined with New Den-O and OOO to fight Shocker's forces, but were eventually defeated. When the order was given to kill everyone, V3 suddenly appeared, asserting that there were more than four Riders. V3 was soon followed by all the other revived riders that came after him, including Shin, as even though Rider history was changed, the people's memories haven't changed.

After the riders were united, they faced off against Shocker's Great Leader. Later, when joined by a force of extra Riders, Shin and all the other riders got on their motorcycles and performed the "All Rider Break", ramming into the Rock Great Leader and defeating it once and for all.
 * Although Shin's human form isn't shown in the movie itself, he has no lines and isn't listed in the credits, Shin is confirmed to be Shin Kazamatsuri by the movie's official website.

Super Hero Taisen
Shin was among the Kamen Riders caught up in the 'Super Hero Taisen' incident. He was presumably sent to the dimensional rift, under the pretense of being defeated, by Captain Marvelous while he was apparently hunting the Riders. When his and Tsukasa's ruse was revealed, Shin and the other Riders appeared through the dimensional wall. Shin then fought alongside all the other Kamen Riders and Super Sentai against Dai-Shocker and Dai-Zangyack's Shocker-Zangyack Alliance. During the final battle, he is seen fighting Hades God Dagon with OhBlue and MammothRanger, and Armadillo Orphnoch and Gormin Sailors with the Boukengers. As Walz Gill and Ackdos Gill start blasting at everybody, Shin is in the background getting tossed into the air with the Gekirangers.

Kamen Rider Taisen
Despite the fact that it was not shown in the movie itself, Shin was killed by a Heisei Rider and was turned into a lockseed.

Shin later appeared when Gaim and ZX released all of the Kamen Riders from their Lockseeds.

Kamen Rider Shin
Referred as "Cyborg Soldier Level 3" (改造兵士レベル3), Shin mutates into a mostly organic insectoid with enhanced strength and regenerative abilities.

Rider Card
Kamen Ride Shin (カメンライドシン) is the Kamen Ride Card which contains the power of Kamen Rider Shin. In All Riders vs. Dai-Shocker, Decade Complete Form Jumbo Formation performed the Final Dimension Kick, a variation of the Dimension Kick, transforming the Shōwa Riders, including Shin, and Heisei Riders into Kamen Ride cards for Decade to travel through as opposed to Final Attack Ride cards before hitting the target.

In theory, this card would allow Kamen Rider Decade to transform into Shin.

Wizard Ring
This Rider Ring which bears the likeness of Kamen Rider Shin is exclusive to Kamen Rider Wizard's Wizard Ring toyline. When used by a WizarDriver wearer, it would be able to summon Kamen Rider Shin.

Lockseed
Kamen Rider Shin Lockseed (仮面ライダーシンロックシード): A Lockseed bearing the likeness of Kamen Rider Shin, created when Shin was defeated in the battle between the Showa Riders and Heisei Riders. The core image depicts Shin's headshot while the lid backside image depicts his signature pose. When inserted into a Sengoku Driver or when channeled through the Showa Rider Lockseed, it would allow an Armored Rider to assume Shin Arms (シンアームズ). It is styled for Gaim, Kurokage, Bujin Gaim, and Kamuro in the toyline.
