She then welcomes them to the Union, but as Tatiana is angry for Andy killing Gina, she attacks him and Juiz makes Andy point his sword at Fuuko, while Tatiana her weapons at Billy and they agree to stop.

They sit on the table and Juiz calls for Apocalypse, who gives them new quests. She tells Nico to analyze it and he tells them they should focus on the first three and prioritize Burn and drop Spoil. Juiz agrees to the plan, but as Fuuko wonders on why they should play those games, Juiz explains that 98 times rules were added to Earth and even if they don't participate, each three months new rules will be added. So they decide to take action and strengthen themselves and one day be able to kill the god that forces them playing this game. Juiz explains that Fuuko can take leadership if she surpasses her achievements and results. Andy decides to take Spoil, disagreeing with their plan, while Juiz decides to participate in capturing of UMA Burn, Eat and Past.

They engage him in combat, where Juiz creates fire from her sword, making Victor realize this was Burn's handiwork. When Fuuko jumps on Victor and explains her unluck will work faster if it was Andy, Juiz tells everyone to protect her while she is able to bring back Andy and activate her ability.

To give Fuuko a chance, she sacrifices all of her points to move Andy and Fuuko to the time of the rewards, which gives out UMA Ghost, allowing Fuuko to continue existing as a ghost, only to be kidnapped by Ruin. With the world now in Ragnarok with the deaths of three of the four Season UMAs, Andy leaves the Union to rescue Fuuko before the end, and Juiz gives him a weapon by throwing it at his chest. Later on, it's shown both the Union and Under working together to stave off Ragnarok as long as they can by gathering UMAs, only for Ghost to have Nico betray everyone by killing all of the UMAs.

Eventually, after Fuuko is revived and she and Andy make it to the Roundtable, Juiz greats them before handing the role of leadership to Fuuko, and then explains a way to save everyone and the origins of Andy. After Andy reaffirms his existence and his love for Fuuko, Juiz tearfully realizes they are the ones who will finish the fight against God. She leaves with Andy and Victor to hold back Sun long enough for Fuuko to loop, using the artifact Rebellion to hold Sun back for 5 whole minutes before dying from the strain.
