Description
Nicolas Vacheron is an 18-year-old Swiss male human, a Lieutenant trainee within the elite pilot corps, The Fraternity. He pilots the semi-organic Buster Machine Vingt-Sept (No. 27), utilizing his "Topless" supernatural abilities—essential for manipulating physics—to operate it. His name originates from the Swiss watchmaker Vacheron Constantin.
As a highly-rated male Topless, Nicolas wields advanced "Physics Infringement" capabilities: particle manipulation, quantum manipulation, entropy reversal, and Clefshin luminescence for light generation. A super-space corridor on his forehead manifests these powers, kept sealed by a "piece seal" outside combat. His combat skills encompass summoning, telepathy, animal possession, reality alteration, and innate mech piloting intuition. Piloting Vingt-Sept amplifies his abilities to mountain-level attack potency, relativistic reaction speed, Class M lifting strength, and interplanetary range via energy beams or telekinesis. Key techniques include the Buster Beam, Buster Harken, Buster Megatech PK, and the Buster Sword—used to solo a Beastron-class Space Monster. He also executes combination attacks like the "Buster X Attack" with fellow pilot Lal'C.
Outwardly relaxed and charismatic, Nicolas downplays his leadership role but exhibits eagerness in combat, often treating missions as performances. He maintains a platonic bond with Lal'C, whom he inspired to become a Topless; their dynamic is marked by professional synergy and mutual respect, with Nicolas affectionately nicknaming her "Princess." He mentors Nono, recognizing her latent potential and covertly assisting her entry into The Fraternity as an auxiliary member despite her lack of manifest Topless powers.
Nearing adulthood—when Topless powers naturally fade—Nicolas experiences profound psychological distress masked by cheerfulness. This fear escalates into desperation, leading him to align with the antagonistic Serpentine Twins' scheme to preserve his abilities. This culminates in a mental breakdown during Episode 5, where he attempts to rape Nono in a misguided effort to harness her status as an "eternal Topless," severing his relationships and marking his moral downfall.
Nicolas's arc concludes with his powers irreversibly fading post-breakdown. His ultimate fate remains unresolved, though it implies departure from active combat and The Fraternity.
