Things continue to deteriorate as the Holy Aurum (Gold) Qwaser finds that she is her own Maria Magdalen while taking Mafuyu captive and deriding Shin'ichiro's subterfuge against her. The expository concourse Friederich Tanner and Shin'ichiro prosecute about the true purpose of the heretic Qwasers Sasha has killed under Athos's orders sets the stage for Sasha to demonstrate great moral strength when he spares Teresa and Elizabeth prior to chasing after Shin'ichiro only to find himself knocked around like a rag doll as Shin'ichiro either dodges or otherwise perverts to his detriment each of his attempted attacks; it is only by channeling his protective desire for both Tomo and Mafuyu into forming the Fresh Blood Sword around Mafuyu's wooden sword that Sasha successfully turns the tables against Shin'ichiro using his full powers. Elizabeth is extremely anguished that Shin'ichiro is in a bad way but respects his dying wish for her to fight alongside Sasha as debris from the roof falls upon him; unfortunately for the hysterical Elizabeth, the Holy Aurum (Gold) Qwaser is still intent upon the »Tsar's Crowning« as she energizes the Imperial Egg to begin assimilating it. Although she is after the Egg for her own reasons, Ekaterina's ranged energy attacks ultimately become the ironic deus ex machina to foil the Holy Aurum (Gold) Qwaser's plans along with emancipating both Mafuyu and Tomo; unfortunately, Friederich is not hostile to taking Tomo as a consolation prize.

While meditating under a waterfall, Mutsumi Sendou reflects on her prologue as Sasha's Maria Magdalen partner to the time when she guided Sasha through how to quickly recharge his soma during battle before demonstrating unto her Qwaser paramour Taisuku Fujiomi the fallacy of the proverb »Love has no obligation for apologies«. Meanwhile at Saint Mihailov's Academy, the anxiety over Tomo's uncertain status is the elephant in the room as Mafuyu grapples with the reality that the Aurum Qwaser will still wield Tomo as his avatar even if a rescue attempt were to succeed. Hana playfully deriding her affection for Sasha does nothing to prepare her for Taisuku and Mutsumi enrolling in the school as transfer students the next morning -- apparently to prosecute some kind of operation for the »Tsar's Crowning«. After waylaying her between classes, Sasha inquires Mutsumi her presence at the Academy only to have his challenge and Mafuyu's »What the hell are you doing!?!« intercession perverted to both his detriment and Mafuyu's before Taisuku contributes to the encounter. The student council president Yumie Hiragi delivering a stern »Keep it in the barn!!!« admonition to the pair prior to becoming the quarry of the Ouroboros Elemental Circuit ultimately becomes the deus ex machina for the illuminating Taisuku and Mutsumi's true objective -- the location and acquisition of the Sword of Maria incantation needed for activating the »Tsar's Crowning« -- the very thing Mafuyu ironically wields against Mutsumi's seductive coercion.

While Jita Phrygianos appraises Tomo prior to a procedure intended to enhance Tomo into becoming a High Maria, Sasha has figured out how to pervert the mechanics of Taisuku's powers to his advantage before racing to Mafuyu's rescue uninterested in Taisuku's prologue as a Vajrapanis; a strategic retreat on Mutsumi's part gives way to Mafuyu and Sasha wondering about the »Sword of Maria« element circuit as they compute their next move. While Ekaterina plays the consummate actress to defuse a teacher's challenge for loitering, Joshua is shocked to find that there is no honor among his teammates when it comes to Tomo's soma; whatever the Adepts' volition for her, it becomes apparent that Tomo is more valuable in one piece -- much to Mafuyu's relief when Tomo sends a »Keep the faith and the home fires burning« video after her day with Astarte who is already a High Maria. Still, even with Tomo having the run of the Adepts' hideout complete with the security detail, the Holy Aurum Qwaser ultimately sees no reason to abandon her plans and Georg Tanner clearly has plans for Mafuyu through that elemental circuit.

Seeing that the circumstances are deteriorating around them, Sasha and Mafuyu desperately rifle through Shin'ichiro's research for clues to help secure the »Tsar's Crowning« along with Tomo's safe return oblivious to the fact that Friedrich seeks to wield Ekaterina in his long-range designs for the icon. Be it Tomo's absence or the experiences of being used as a diary cow, Miyuri has somehow detected a deviant diagnostic with Mafuyu who she encourages to attend Ekaterina's birthday party with Sasha who is shocked to learn that the infirmary nurse Urada Oikawa has extensive data about the war Athos is prosecuting with the Adepts at St. Mihailov's Academy along with a prologue of assisting Yuudai with his research on the »Tsar's Crowning« alongside Shin'ichiro before handing Sasha the key to Yuudai's research. While Sasha ultimately finds it no trouble at all to defeat Elizabeth in the crazed artificial beast incarnation, Friedrich still accomplishes his objective of delivering the distraught Ekaterina an urgent exhortation to catalyze the advent of the »Tsar's Crowning« icon; considering the destruction of Anastasia and Hana's friendship overtures being subsequently repulsed that evening along with her abrupt departure, it is not out of the question to say Ekaterina is giving it some thought.

The circumstances continue to deteriorate as the Adepts join forces with the Ancient Regime in a sort of tenuous unholy alliance as the Holy Aurum Qwaser declares the time is ripe to advance toward the »Tsar's Crowning«; almost if they had sensed this, Sasha and Mafuyu desperately search around for the Aquatic Sanctuary where the Icon is held only to find that there is a specific set of circumstances under which it can be found. The Hydrogen Qwaser Milk drawing a lot of attention due to her gas mask as she leads Jita Phrygianos through buying a cake in a store becomes the backdrop for Mutsumi and Tasuku to pick a fight with the two Qwasers while Friedrich abducts Mafuyu in order to avail the Sword of Maria elemental circuit within her body. Even with Hana's syllabus of Ekaterina being abruptly missing in action, Sasha is shocked to find the irony that Ekaterina is ultimately the most dangerous adversary on the scene as she threatens Mafuyu's life prior to the advent of the Aquatic Sanctuary; as if to rub salt in the wound, Ekaterina arrogantly decides to refuel herself with Mafuyu's soma caring nothing that the most power she will have in the Holy Roman Empire version 2.0 is as Friedrich's second-in-command.

Almost as soon as Ekaterina devotes herself to partaking of Mafuyu's soma, the Sword of Maria elemental circuit demonstrates the mechanics behind its immense power as Friedrich leads the charge with his brother Georg toward the Aquatic Sanctuary as he phases out with Ekaterina and Mafuyu along with two of the Adepts Qwasers certain that his subterfuge for the »Tsar's Crowning« will pay off. Tasuku and Elizabeth volunteer to stalemate Jita and Wang Chen's proximity injunction while Sasha intercepts the Tanner brothers as they are about to throw Mafuyu into the corrosive energy matrix surrounding the Sanctuary only to find to his horror that they are as deadly adversaries as they are devious scoundrels. The ironic silver lining in this confrontation is that the Tanner brothers' greed ultimately becomes their own worst enemy when their respective powers going out of control becomes the forum for Ekaterina to see the light as Hana repels Friedrich's chivalrous lechery before delivering a blistering reproof of Ekaterina's gullibility complete with a pair of »What the hell are you using for brains!?!« slaps across the chops; Sasha successfully destroying the Tanner brothers' combined avian form catalyzed by Ekaterina and Elizabeth's joint efforts along with those of Tasuku offers cold comfort to the Holy Aurum Qwaser ready to claim the spoils.

When the two come together, Sarui Sue's birth goddess of swords and the sword of fresh blood appears. Sasha is astonished to meet someone. The Golden Qwasar reaches out to Sasha to join her in her quest to become a god together. Sasha is furious and her power goes out of control. She looks like a monster. Neither Mafuyu nor Katya can stop her anger. The golden qwasar has even more power than Sasha. What will decide the fate of the battle between the two?

The ancient battle between the qwasars has come to a temporary end, and the school and Mafuyu's breasts are completely back to normal. Mafuyu worries that Sasha will be disappointed by the fact that her breasts have become smaller. She tries Miyuri's special breast augmentation products with Fumika and Lizzy, but they have no effect. Sasha comes to Mafuyu, who is disappointed. Sasha, who was given one day off by Athos, invites Mayuri on a date...!
