Summary
Hakuryuu asks Sinbad about what if a king's justice is misguided, Sinbad replies it's the same as a king abandoning his duty. Then, Hakuryuu further explains that what's "right" changes over time and compares to himself during the Kou Empire Civil War and during the aftermath. He then asks Sinbad if his justice has ever wavered. Sinbad finds Hakuryuu arrogant to question him during their trial and replies that he believe in himself in order to get rid of war and then take that as something to be prideful of. When Hakuryuu asks Sinbad about destiny and trusting his comrades, Sinbad argues he does believe in them and that they have a role. Mentioning Judar's answer, everyone can only play a single role because they differ in quality and capacity of their vessel.

As Sinbad mentions erasing the concept of nations and gather power, Hakuryuu argues power should be shared. Sinbad states there is no one he can share his divine power as there is no one else to lead to the world. When Hakuryuu asks Sinbad if there is no one better than him, Sinbad replies that's why he has to witness the fight to end which reminds Hakuryuu about Sinbad and Aladdin's earlier answer, wishing to erase his only regret.

Outside, Aladdin continues to explain Sinbad's motives to erase his only regret because he has found challengers whose Rukh weren't overwritten. After Valefor's dungeon collapses, Alibaba and Aladdin realizes Sinbad isn't persuading them as he has another objective.

In the third dungeon which the trial is conducted by Zepar, Sinbad introduces Serendine and explains he obtained Zepar by fusing with her Rukh just like how Alibaba did to Kassim. While the two Djinn Equip, he then asks them a question, "should humans live according to their own will or should they be guided by others?"
