Otherworldly Wave

Otherworldly Wave (異世界の波) is the seventy-sixth chapter of The Rising of the Shield Hero manga adaptation.

Synopsis
With Naofumi and Kizuna's parties united at last, they must fight a new wave within Glass' World. How will they work together despite their checkered history?

Summary
A new wave has appeared within Glass' World. With both parties of heroes finally united, they work together to repel the enemy. As two Legendary Heroes, both Kizuna and Naofumi work together to fight against the wave boss with relative ease. As the dimensional crack from the waves close, the heroes clean up the remaining monsters.

Back in their castle, Kizuna severely chastises L'Arc, Glass, Therese and their country's leadership for attempting to invade Raphtalia's World. Glass tries to protest, however she eventually reveals the main reason she did so was to protect Kizuna. Kizuna is angry at Glass for her "short-sightedness" and proposes that the purpose of the Legendary and Vassal Heroes are not to defeat other worlds to protect their own but to suppress the wave in general. Ethnobalt arrives to give merit to Kizuna's theory. He recently reveals that he had found book in an ancient language which describes the true nature of the waves. It is possible that they might be able to protect their world from the waves without destroying other worlds.

Seeing that they no longer need to fight against each other, the heroes of Glass' World apologize and are thankful that they don't need to attack their new friends. The two parties agree to cooperate from now on and decide to defeat Kyo. Meanwhile, Kyo has reached his laboratory and is now working on his own nefarious experiments.
