An anthropomorphized firearm from the Romanov era, Aleksandr embodies a motif crafted for Tsar Aleksandr I of Russia. Commissioned by Ekaterina II out of affection for her grandson, she tasked her favored gunsmith with creating a set of rifles exclusively for him. This motif features an elegant wooden grip adorned with delicate gold and silver embellishments, reflecting a graceful aesthetic.

In human form, Aleksandr stands 180 cm (5'11") tall with a slender build weighing 63 kg (139 lbs). He possesses pale skin, lavender purple eyes, and pale silver hair reaching mid-back, typically worn loose but sometimes tied in a low ponytail. His expressions frequently flicker between a gentle smile and an earnest, determined demeanor.

Aleksandr speaks with refined formality and unwavering politeness. His dialogue often includes phrases like "Please leave everything to me, Master" and expressions of profound gratitude for the chance to serve. He demonstrates deep loyalty to his summoner, referred to as "Master," emphasizing his commitment to duty despite acknowledging his initial lack of combat experience. He harbors a respectful rivalry with Ekaterina, aspiring to earn her recognition through battlefield prowess.

He spent significant time inactive within a winter palace environment before awakening in a devastated post-nuclear war world. Aligning with a resistance movement against the oppressive World Empire, he fights as a Noble Musketeer—a human incarnation of an antique gun—alongside others of his kind. His abilities include unlocking an "Absolute Noble" mode during combat, enhancing his capabilities against adversaries representing contemporary Empire firearms.

Aleksandr's interests encompass Russian tea culture, ice skating, and chess. His relationship with Ekaterina is significant, his motif directly tied to her legacy of craftsmanship and familial devotion.
