Kamen Rider: Top-Tier Drivers, Granting Eternity and Bestowing Divine Skills

New to Fuuto, a young man has a Lost Driver that can grow on its own and an Eternal Memory. If he lacks equipment, it powers up. If his body is weak, it strengthens him. If the enemy is strong, it evolves. The Driver does almost all the fighting for him.

Whenever danger strikes, the Driver is even more anxious than its owner. The moment a psychic attack lands, it evolves in anguish to gain resistance. If its battle instincts aren't good enough, it feels guilty and improves itself. If there are too many enemies, it figures out a finishing move on its own. The young man only has to insert a Memory and press a button on the belt. The Driver eagerly takes care of everything else.

Executives from the Museum come after him and personally join the assault. Just as the young man is about to fight, the Driver has already mapped out every attack route and arranged the precise timing of each strike. Nasca is defeated, and the Taboos are shocked. Even the Gaia Library can't identify where this duo came from.

But the young man knows this is nowhere near the end. The Driver is still growing, and even he can't predict what it will do next. When the darkness of Fuuto starts paying serious attention to him, just how far will that Driver go to prove itself?
