AL: Kamen Rider Prototype

In the near future, humanity lives under the shadow of mysterious mutated beings known as Evolves-former humans transformed by parasitic organisms born from the same darkness that once threatened the world. Neither fully human nor fully monster, Evolves prey upon those with high Magi potential, especially young warriors known as Lilies, whose power has become essential in the war against the Huge.

To combat this new threat, humanity develops experimental anti-Evolve technology by combining biological science, ancient relics, and Magi-based engineering. Among these weapons is the forbidden living armor known as Prototype-a bio-armor system created before modern CHARMs, designed not only to fight monsters, but to evolve alongside its user.

However, Prototype is no ordinary weapon. It rewrites the user's body, awakens primal instincts, and risks turning its bearer into the very thing they are meant to destroy. Many test subjects failed. Some lost their minds. Others became Evolves themselves.

Then, after years of silence, the armor chooses a new user: Takeya Yuito, a rare male Lily with unusually stable compatibility with Prototype. Though officially assigned as a student advisor at Yurigaoka Girls' Academy, Yuito secretly becomes the warrior who stands between the Lilies and the monsters that hunt them.

Wearing the living armor and carrying the burden of a weapon feared by both humans and Evolves, Yuito fights not as a perfect hero, but as someone who still wishes to remain human.

As the Evolves grow stronger, old secrets from GEHENA resurface, and the truth behind Prototype's creation begins to awaken. Yuito must face not only the monsters outside the Garden walls, but also the monster slowly growing within himself.

Because in a world where evolution means survival, one question remains:

Can a prototype become a hero before it becomes a monster?
