He is the main protagonist. Tomo literally stumbles over the Russian born Alexander during her home commute with Mafuyu after a particularly difficult school day. After Mafuyu and Tomo nurse him back to health, Alexander wastes no time demonstrating his powers as a Qwaser with the element of Iron as he stalemates and eventually vanquishes the Magnesium Qwaser with such capabilities as forming an enormous black scythe that is at least twice his size along with vibrating the atoms in the iron to generate the immense heat necessary to forge alloys of iron without the need for an external blast furnace. Besides the hostile heretic Qwasers whose neutralization Athos charges him, Alexander is very austere with anyone that decides on her own to refer to him as »Sasha«and has a difficult time adhering to the social mechanics of Japanese society much to Mafuyu's frustration in the early going. Sasha's primary vendetta with the Adepts is the murder of Olja (オーリャ Ōrya?, Оля) at the hands of the Aurum (Gold) Qwaser who exiled him with a large scar on the left side of his face shaped like an inverted Eastern Cross that tends to bleed in response to Sasha's excitement during battle -- the acme of which characterized by Sasha's left eye becoming red and the scar glowing prior to bleeding heavily during power-down. Driven by his bitter prologue with the Adepts and the parallels that he sees between Tomo and Olja, Sasha's ferocity reaches its zenith when the Adepts target Tomo for her high-quality soma; during his time with Mafuyu, Sasha comes to realize the infinite value of human life as he demonstrates a copious contempt for the Adepts endangering innocent people. Aside from the comedy of refracting Miyuri's persecution to her detriment and the situational remarks in Russian (though such quotations are often authors' errors), Sasha is shocked to find that Mafuyu gives as good as she gets when he obdurately ignores the social conventions of human civilization and forces him to partake her consummate cooking -- particularly when it is his favorite dish borscht. Over the course of the series, Sasha's arsenal expands from his trademark scythe and kunai to a katana-like sword he wields in tandem; even though he rejects the prospect in the early going, Sasha and Mafuyu begin to become attracted to each other even as they deny it when confronted about the prospect. He was involved in the most serious confrontations that happened in the series, the last one being the one against Shin'Ichiro Ootori, where he managed to reach the 4th (on a scale of eight) grade of elemental control. Nevertheless, he was recently forced to separate from Mafuyu, much to his dismay, and undertake training sessions to prepare for future confrontations but came back and had his first kiss with Mafuyu.
