Based on flintlock pistols crafted for Emperor Napoleon by Nicolas Noël Boutet at Versailles, Nicola remained Napoleon's cherished companion even during exile on Saint Helena and was later bequeathed to Napoleon's son. He manifests as a petite figure, standing 148 cm tall with fair skin. His dull, dirty blond curly hair forms a chin-length bob, featuring long bangs that conceal his left eye, while his visible right eye is violet, often accompanied by a mischievous smirk. He shares an inseparable bond with his twin brother, Noël, both once part of Napoleon's personal arsenal.

Driven by studious ambition, Nicola strives to emulate Napoleon's greatness through diligent study, frequently contrasting his own dedication with the perceived foolishness of adults. His passions encompass academic pursuits like reading and battlefield analysis, alongside a fondness for strawberry-flavored crepes. This commitment stems from deep admiration for Napoleon, motivating his aspiration to become "a great person" worthy of his former master.

Functionally, Nicola and Noël represent a matched set of pistols renowned for their artistic craftsmanship and historical importance, serving not only as battlefield weapons but also as symbols of status and refinement during Napoleon's reign.
