Commercial
"Get rid of stains and rust with Kure 5-56."

- Kokoro

Kamen Rider 1 (Tetsu Inada) is standing in a garage, watching as a young Rider Squad member named Kokoro and his father work on their respective bikes, with that of the former being a small cycle based on Kamen Rider's Cyclone, when someone knocks on the door asking to come in. Kokoro's father attempts to lift the shutter door only to find himself unable to open it as it is too rusty. Kamen Rider reminds Kokoro of what to use to tackle rusty doors: Kure 5-56. After performing the henshin pose with Kamen Rider, Kokoro uses the Kure 5-56 spray to refresh the rusty door before opening it, only to hastily close it again when he sees five Shocker Combatmen waiting outside.
