Batman and the Justice League, Vol. 3

Rui, a young boy from Japan, comes to Gotham City in search of the truth behind an accident that lead to the disappearance of his parents. Instead, he finds himself caught up in a plot by Lex Luthor and The Joker to spread chaos and conquer the world by controlling the power of the mystical Ley Lines running throughout the Earth.

Encouraged by The Joker and in the thrall of the Ley Lines, Aquaman's half-brother Orm has summoned a massive tidal wave to flood Gotham. Batman and Aquaman engage in battle with the Ocean Master to try and stop this destruction. While Aquaman seeks to reason with Orm, Batman is determined to stop him by any means necessary. Superman soon joins the fray, but the challenge becomes even greater when the mysterious oni known as Akurou summons a giant snake to engage the heroes.

New villains arrive on the scene - Sinestro, Reverse-Flash and Cyborg Superman. Soon Luthor and Joker decide to unite them all in an Injustice League. Meanwhile, the nexus point of the greatest congestion of Ley Lines on Earth is revealed to be directly under the Batcave. Rui, under the protection of Wonder Woman, must undergo a transformative ritual in order to save his parents and perhaps the world itself.
