Tear Jerker / Yu-Gi-Oh! World Legacy

• The end of the Mekk Knight / World Chalice / Knightmare conflict. Ib is freed due to the power of the Team Pet, and in order to prevent Lee from seizing control again, she kills herself on Auram's sword. Auram is left to cradle her dying body, while Beckoned / Ningirisu looks extremely battered and despairing of this. This, after they journeyed to fight the Mekk Knights to free Ib, only to find her corrupted and fused with Lee. Little wonder poor Auram fled, and by all appearances, swore off his own name in grief.
  • It gets worse years later, after Ningirsu—having since changed his name to Longirsu—constructs a mechanical body for Ib and uses the power of a World Legacy to awaken the Orcust army and begin a huge battle with Avram's Crusadia faction. That the two are fighting each other after being brothers-in-arms before is bad enough—but then Ib's robotic body turns into another Knightmare, revealing that Lee's corruption may well still reside within her, and therefore that Ib took her own life for nothing.
• By the end of the World Chalice arc, a revived Ib, Ningirsu and Imduk are the remaining survivors of the World Chalice archetype, though Ningirsu has been rebuilt as the robotic knight Girsu, tasked with the Mekk-Knights' duty of defending the world. Auram had to become the new creator god Avida in order to undo the damage wrought by Lee's machinations. Ib (now Lib) now walks the earth to seal away the World Key, and has to live with the grief of losing Auram.
