After beating Autumn, the idea of the Union & Under working together sounds great and idealistic. However, at the end of the Under is simply an organization that prioritizes what Juiz declares its goals are, which is justice for everyone, not the majority. As expected, Rip won't budge since he needs Ark to travel back in time to save Latla's sister whom he loved.
The idea of these sides teaming up isn't an idea only wanted by Fuuko as Juiz asks Billy to join forces again. Of course, it makes sense for Juiz to not want to fight against Billy. Though she does offer a good amount of knowledge and the Ark is a vital tool, thus keeping both Winter and the Roundtable hostage leaves Billy in the driver's seat. Funny enough, it was because of the Ark that Juiz learned that the artifacts were made by God to kill God. The thing with Juiz it may or may not be bullshyt that Ark is only good for one more round. After all, who knows how many loops she has gone through. And why suddenly Ark can be only good for one more trip? There is something suspicious about this. Though two key things, Juiz says that is important. The first we know that her resolve to kill God we know comes from the heart, as Victor hates to see Juiz suffer. Juiz wanted to make Victor smile. Victor knew that banking on more chances seemed silly, and it was painful for both of them. While Juiz just believed, they needed only one shot with the right team, and they could do it. Fuuko being the wild card that can ensure them the victory. After all, she would not be present if they fail again and her unluck can come up clutch.
Though given that Billy made all these preparations, it would have been silly for him to act all friendly with Juiz again. Though it is heartbreaking to hear that all this time since he joined the union, he never trusted anyone. He used everyone for his gain. Not so surprising, the fight starts between Billy and Juiz. Burn vs Spoil is an interesting fight, though it seems in that fight burn wins. Makes sense, even if something is spoiled, you can burn it away. Though, Spoil mentions how Concept type Umas like Winter look down on phenomena type Umas like Spoil and Burn. Though the fact that Juiz's unjustice works on Burn signifies his sense of justice, implies loyalty to Billy. To meet their maker, but does this differ from God?
Though, as Juiz uses Unjustice on Billy, he ends up beating her. Would that imply that what Billy said previous was a lie? That fighting is not what he wants? The reason he did not want to use Unjustice on Juiz could follow the same logic. Although as Billy indicates that capturing Unluck is the next goal for them. Given what Juiz said, it only makes sense to go get the biggest key to beating God. Of course, the other members of Under may have thoughts regarding that decision. Also, I expect Juiz not to give up on Billy.
While we got, Andy and Fuuko meeting up with Shen and Mui. A little bit of Shen's past is revealed. As him and his sister didn't have the best life, but Shen did everything if it meant protecting her. He even trained under Feng to provide the benefits for her. Though now Shen couldn't protect Mei, so him teaching under her seems reasonable. Given the stature of the opponent that faced Andy, which intrigued Shen to fight, made you wonder if this was Mei. Though it was revealed that this one is Shen's master, the one who is responsible for killing Mei. Though, it sounds like when Shen's Untruth manifested is when he had to hold on to Mei, and she let go. Technically speaking, Shen is responsible for Mei's death if that were the case. Of course, as Luo mentioned, having the siblings fight each other is just heartless. The artifact that Feng carries can seal anyone he kills and uses them, Jiangshi. Given Feng's words, Mei shouldn't be in there. Heartbreaking to learn of Shen's goal and motivates. Even more so, who is Mui, and why does she look so similar to Mei?
No surprise, Andy and Fuuko weren't standing by and jumped right in to fight Feng. Despite trying to find out what type of negator Feng is, he showcases nothing, but his pure hand-to-hand combat skills. Though given that he became 150 years younger when Rip got 15 years younger just makes his age suspicious. Unless he can negate death, making him undeath? Though, Feng's motivation to get Andy to fight doesn't work too well since protecting Fuuko is his goal. Though, I wonder how the tag team of Andy and Shen will work. Shen can't use Untruth on Feng because he despises him. However, him using it on Andy could provide an interesting idea. On a final note, Feng learning that bone fractures don't trigger Undead's repair abilities is interesting to note.
