About

The protagonist, Ren Kamishiro (Rider 1), was granted the ability to manipulate a special energy called 'Element Particles' by a mysterious organization. However, as a side effect, his form becomes more monstrous than human when using it, and his personality grows savage with prolonged use. Ten years ago, an explosion occurred at the research facility. While escaping with seven other test subjects of similar age, he discovered a transformation belt and three transformation items (Wind: martial arts style; Flame: swordsmanship; Earth: mace and defense) that allowed him to stabilize and diversify his energy. During the escape, a girl he was close to fell and was about to be caught in an explosion; he threw her to safety but was caught in the blast himself. He lost his memories of the experimentation, remembering only that he can transform and possesses special powers. Now a university student, he fights monsters to protect the peace and recover his memories while navigating campus life. 1: Element Particle-based 'Dual State' Gimmick Transformations are divided into 'Stable' and 'Overload' forms. ✅ Stable: Controlled form via the belt (Humanoid, elemental expression possible) ⚠️ Overload: Mutation into a monster-like form during emotional outbursts or prolonged use (Powerful but uncontrollable) After a certain incident, the Overload form begins demanding control over him → Internal struggle element 2: Deepened Elemental Gimmicks Wind: Light aerial combat/multi-jumps/evasion-focused – Linked to 'flexible and free emotions' Flame: Aggressive and linear style – Linked to 'anger and fragments of memory' Earth: Slow but overwhelming destructive power – Linked to 'responsibility and protective instincts' → Emotions and elements are organically connected. Belt and Item Names: Belt -> Core-Raidriver / Transformation Items -> Core Stones Monster Race Name: 'Obverse' – Beings born from Element Particles that feed on desires and emotions. A growth drama as a Kamen Rider, supernatural/identity conflicts behind the scenes of everyday school life, and a story of emotional balance designed around internal turmoil and memory fragments. Features devices like 'urban legends', 'risk of identity exposure', and 'an extremely ordinary person who becomes the key to shaking the protagonist's life'. 🔹Background Summary The protagonist is already active as Kamen Rider, but his identity is kept strictly secret. Strange incidents caused by Element Particles continue to occur near the city center and the school. People talk about these as if they were 'urban legends'. → e.g., 'When a monster appears, a mysterious hero defeats it.' 🔹Story Progression A transfer student, Yuu, gets caught up in a monster appearance incident on their first day. (e.g., A monster absorbs a student's desire and goes berserk in the school gym) The protagonist transforms where people aren't looking and quickly suppresses the monster. → The protagonist usually tries to disguise himself by minimizing weapons/forms. Yuu witnesses the scene after the fight and the remaining Element Particles (light, traces, etc.). → 'No way... is it real? The Rider from the urban legends?' The day after the incident, Yuu begins to observe the protagonist closely. → After subtly tracking physical abilities or reactions in crisis situations, Yuu discovers the protagonist is Kamen Rider and becomes a reliable ally and friend.
