In telling the story of Yuri to Keisaku and Eita, Margery asks them what they would do if they were Flames Hazes who had been told not to follow her, but she was in danger. The two aren’t entirely sure, so Margery continues her story. Back then, she had faced off against Annaberg at the Empire State Building and had turned into her werewolf form. Annaberg’s special characteristic was that he used steam to obscure presence, and he traded places with Sydonay who was waiting at the top of the building. In response to Sydonay joining the fray, Margery multiplied her werewolf form and counterattacks. Sydonay dived towards Annaberg before the explosion went off, and afterwards, Annaberg launched into a speech about the acceleration of civilization and the power of it that changes the world. Margery had then heard Yuri warn her, but she turned around too late and got slashed through her shoulder by Sydonay. Yuri had been communicating with her from outside the fuuzetsu via a moth, but Sydonay promptly destroyed it. Knowing that Margery was in trouble, Yuri summoned all the moths in the city to mix with his flame and surrounded himself with a giant mass of energy.
Having reverted back to her human form because of her injury, Margery was about to be finished off by Sydonay when Yuri suddenly flew in and cut Sydonay in half. This didn’t stop Sydonay though, so Margery chased him while Yuri attacked Annaberg. Valac had warned Yuri that he couldn’t keep this up for long because of the extreme power consumption, but Yuri nevertheless found this wonderful and thought about all the people he could save with it. When Annaberg tried to shoot him in an air battle, Yuri turned around and met Annaberg head-on, destroying the Tomogara with his power. Afterwards, Valac urged Yuri to leave Sydonay to Margery because he had run out of power, but he went anyway. Margery and Sydonay had reached a bit of a standoff, and Sydonay was feeling that there was no point in continuing this since Annaberg was dead. Both of them notice Yuri approaching, and Marchosias proposed a pincer attack to Margery, but he noted that it would require her to risk her life. Margery knew that she couldn’t do that until she got revenge on the Tomogara from her past, and she watched as Sydonay cut through Yuri. Sydonay followed this up with an energy blast, so Margery fired one too, and the combination vaporized Yuri, leaving only his glasses behind. After that battle, Margery had visited East Edge to give him the glasses, and she had reflected on how she didn’t hesitate.
Back in the present, Marchosias explains that if Yuri hadn’t come, Margery and Sydonay would have continued fighting until one of them died. It was thanks to Yuri that they were able to bring a halt to the battle. Yuuji meanwhile is still training and eventually succeeds in creating a fuuzetsu. However, Shana and Alastor are shocked to see that the color of Yuuji’s flame is silver – the same silver that Margery vows to kill no matter who or what gets sacrificed.
I guess the ultimate lesson in all this is that Margery will stop at nothing until she has her revenge, no matter what she has to do. I’m glad that they immediately made that relevant by having Yuuji’s flame be silver because now we know that some sort of showdown is probably coming when Margery finds out. It’s not clear yet though whether the silver is an indicator that Yuuji holds what Margery is after or if the color is just a coincidence. Regardless, I imagine some big things will probably happen now.
Having said that, next week doesn’t seem to be a direct continuation of this cliffhanger (if you could call it that). It appears to be about the return of Yuuji’s father instead, which is interesting in its own right, but it remains to be seen if he plays a significant part in the story or is only there for moral support. Unfortunately, the preview indicates that there’ll be an animation quality drop, but given how good these past couple of episodes have looked with all the battles, that’s not too surprising.
