On this episode, Sora disappeared. Meanwhile, Shiro investigates the disappearance while Steph and Jebril lost their memories of Sora.
As I mentioned on my previous post, I take it back. That was no minor plot and it's actually part of the Blank duo's plan on the main plot. Other than that, they explained a lot on why this plot got triggered which was very awesome. Now since Shiro and Sora completed their goal on this episode, will they face the Eastern Union on the next episode? So in conclusion, awesome plot and plans explained.
Conclusion: Awesome plot and more details on their plans.
